After reading
https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.70/autoconf.html#Specifying-Target-Triplets,
my understanding is that this change should mostly be a no-op, as
--build defaults to the output of config.guess, however, this may be
slightly more correct
> For historical reasons, whenever you specify --host, be sure to
> specify --build too; this will be fixed in the future.
and will quell some warnings in depends (#16354). If anything, this
also explicitly enables cross-compilation mode when `--host` differs
from `--build`.
As for "fixed in the future", this is the case for Autoconf 2.70+.

This PR is the third and final piece of the basic Android support puzzle - it depends on https://github.com/bitcoin/bitcoin/pull/16110 and is related to https://github.com/bitcoin/bitcoin/pull/16883. It introduces an `android` directory under `qt` and a simple way to build an Android package of `bitcoin-qt`:
1. Build depends for Android as described in the [README](https://github.com/bitcoin/bitcoin/blob/master/depends/README.md)
2. Configure with one of the resulting prefixes
3. Run `make && make apk` in `src/qt`
The resulting APK files will be in `android/build/outputs/apk`. You can install them manually or with [adb](https://developer.android.com/studio/command-line/adb). One can also open the `android` directory in Android Studio for that integrated development and debugging experience. `BitcoinQtActivity` is your starting point.
Under the hood makefile `apk` target:
1. Renames the `bitcoin-qt` binary to `libbitcoin-qt.so` and copies it over to a folder under `android/libs` depending on which prefix and corresponding [ABI](https://developer.android.com/ndk/guides/abis.html#sa) `bitcoin-qt` was built for
2. Takes `libc++_shared.so` from the Android NDK and puts in the same place. It [must be included](https://developer.android.com/ndk/guides/cpp-support) in the APK
3. Extracts Qt for Android Java support files from the `qtbase` archive in `depends/sources` to `android/src`
There is also just a tiny bit of `ifdef`'d code to make the Qt Widgets menus usable. It's not pretty but it works and is a stepping stone towards https://github.com/bitcoin/bitcoin/pull/16883.

Pull request description:
Creating the dll subdir is no-longer required.
We can drop our wingen patch.
One issue that came up in [#19867](https://github.com/bitcoin/bitcoin/pull/19867#discussion_r483516359):
> unrelated to this change but: why are we inserting the architecture in here, seems like something not necessary to reveal
> My assumption is that it was being inserted to make depends more deterministic. However I think we can improve this, as there's no reason to reveal more of the version information either. Could leave the version as is /2.0 and either drop the architecture, or insert something else?
I've dropped our `sed` and added a patch that just removes the OS string and miniupnpc version from the User-Agent. i.e:
```bash
# master
strings depends/x86_64-apple-darwin19.6.0/lib/libminiupnpc.a | rg -i User-Agent
User-Agent: x86_64-apple-darwin19.6.0, UPnP/1.1, MiniUPnPc/2.0.20180203

```
Note that built unmodified (22c1386351), the User-Agent would be:
```bash

A fix for QTBUG-34748 was introduced in #5915 (v0.11.0, Qt 5.2.1).
QTBUG-34748 was fixed in version 5.3.0.
The separated patch file, provided by #5915, was dropped in #12971 while
bumping Qt to 5.9.4 (5.9.6). But libxcb.mk remained unchanged.
This change reverts #5915 for libxcb.mk.

bd49ac4168 build: fix libnatpmp macos cross compile (fanquake)
Pull request description:
Currently, our cross-compile of libnatpmp for macOS doesn't work at all.
The wrong archiver is used, which produces an archive the linker doesn't like.
This becomes clear when configuring:
```bash
configure:25722: checking for initnatpmp in -lnatpmp
configure:25747: env -u C_INCLUDE_PATH -u CPLUS_INCLUDE_PATH -u OBJC_INCLUDE_PATH -u OBJCPLUS_INCLUDE_PATH -u CPATH -u LIBRARY_PATH /home/ubuntu/bitcoin/depends/x86_64-apple-darwin18/native/bin/clang++ --target=x86_64-apple-darwin18 <trim> -Wl,-headerpad_max_install_names -Wl,-dead_strip -Wl,-dead_strip_dylibs conftest.cpp -lnatpmp >&5
ld: archive has no table of contents for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```
Fix this by using the right `ar` (we do the same for upnp).
While we're at it, fix the build so that we are using our c/ppflags.
In practice this basically means building with `-O2` rather than `-Os`.
Note that this fixes an issue that is also fixed by #21209. However, given there are reservations about updating to use a newer libnatpmp source, we should just fix this for now.

Pull request description:
This replaces `boost::shared_mutex` and `boost::unique_lock` with [`std::shared_mutex`](https://en.cppreference.com/w/cpp/thread/shared_mutex) & [`std::unique_lock`](https://en.cppreference.com/w/cpp/thread/unique_lock).
Even though [some concerns were raised](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-726214696) in #16684 with regard to `std::shared_mutex` being unsafe to use across some glibc versions, I still think this change is an improvement. As I mentioned in #21022, I also think trying to restrict standard library feature usage based on bugs in glibc is not only hard to do, but it's not currently clear exactly how we do that in practice (does it also extend to patching out use in our dependencies, should we be implementing more runtime checks for features we are using, when do we consider an affected glibc "old enough" not to worry about? etc). If you take a look through the [glibc bug tracker](https://sourceware.org/bugzilla/describecomponents.cgi?product=glibc) you'll no doubt find plenty of (active) bug reports for standard library code we already using. Obviously not to say we shouldn't try and avoid buggy code where possible.
Two other points:
[Cory mentioned in #21022](https://github.com/bitcoin/bitcoin/pull/21022#issuecomment-769274179):
> It also seems reasonable to me to worry that boost hits the same underlying glibc bug, and we've just not happened to trigger the right conditions yet.
Moving away from Boost to the standard library also removes the potential for differences related to Boosts configuration. Boost has multiple versions of `shared_mutex`, and what you end up using, and what it's backed by depends on:
* The version of Boost.
* The platform you're building for.
* Which version of `BOOST_THREAD_VERSION` is defined: (2,3,4 or 5) default=2. (see [here](https://www.boost.org/doc/libs/1_70_0/doc/html/thread/build.html#thread.build.configuration) for some of the differences).
* Is `BOOST_THREAD_V2_SHARED_MUTEX` defined? (not by default). If so, you might get the ["less performant, but more robust"](https://github.com/boostorg/thread/issues/230#issuecomment-475937761) version of `shared_mutex`.
A lot of these factors are eliminated by our use of depends, but users will have varying configurations. It's also not inconceivable to think that a distro, or some package manager might start defining something like `BOOST_THREAD_VERSION=3`. Boost tried to change the default from 2 to 3 at one point.
With this change, we no longer use Boost Thread, so this PR also removes it from depends, the build system, CI etc.

Environment variables and search paths can drastically effect the

Include these in our id string to mitigate against false cache hits.
This was missed in #20419, and the update before that, so just
make this un-versioned so that we don't have to worry about it.
This is fine, because it's just for downloading sources.
Instead of doing the awkward /bin path prepending at config.site
creation time, set darwin_{CC,CXX} in a way that fully determines the
program's path (clang/clang++) similar to how AC_PATH_{TOOL,PROG} would
do.
Also see the added comment block in depends/Makefile for more context on
determining $PATH for our config.site.
clang warns when a command line option is unused, and some of our tests
use Werror, so unfortunately we cannot use this flag to pin our linker
for now. Leaving this commit in for future reference, as it would be
great if there's more granularity to Werror and we can be explicit about
what linker we want to use.
Prior to this commit, when int_vars was called for packages, it would
immediately expand the "single-dollar variables", which may be defined
in terms of variables which are not yet determined (e.g. variables
defined in package/*.mk, which are included after int_vars is called).
This is required for the next commit as after that commit, for darwin
cross-builds:
0. int_vars is defined in terms of $(1)_cc
1. $(1)_cc is defined in terms of darwin_CC
2. ... which is defined in terms of clang_resource_dir
3. ... which is defined in terms of native_cctools_clang_version
4. which is undetermined at the time when int_vars is being expanded and evaluated
