- Use 4.19 for riscv64 (earliest LTS release w/ riscv64 support)
- Use 4.9 for all others (second-oldest LTS release, released in
combination with glibc glibc 2.24 in Debian stretch)
We use these flags in our test-security-check make target, but they are
only available because debian patches them in.
We can patch them in for our Guix builds so that we can check the sanity
of our security/symbol checking suite before running them.
Support for riscv64 in glibc landed in 2.27 so it's unavoidable that we
use 2.27.
Running a Bitcoin build with toolchains based on 2.24 for platforms
other than riscv64 seem to produce binaries which do not have 2.17
symbols. So use 2.24 since it's more recent and maintained by Debian
Stretch.

macOS:
We use a compile flag ([-mmacosx-version-min=10.14](https://github.com/bitcoin/bitcoin/blob/master/depends/hosts/darwin.mk#L96)) to set the minimum required version of macOS needed to run our binaries. This adds a sanity check that the version is being set as expected.
Clangs Darwin driver should infer the SDK version used during compilation, and forward that through to the linker. Add a check that this has been done, and the expected SDK version is set. Should help prevent issues like #21771 in future.
Windows:
We use linker flags ([-Wl,--major/minor-subsystem-version](https://github.com/bitcoin/bitcoin/blob/master/configure.ac#L683)) to set the minimum required version of Windows needed to run our binaries. This adds a sanity check that the version is being set as expected.

e2c40a4ed5 guix-attest: Error out if SHA256SUMS is unexpected (Carl Dong)
4cc35daed5 Rewrite guix-{attest,verify} for new hier (Carl Dong)
28a9c9b839 Make SHA256SUMS fragment right after build (Carl Dong)
Pull request description:
Based on: #22075
Code reviewers: I recommend reading the new `guix-{attest,verify}` files instead of trying to read the diff
The following changes resolve many usability improvements which were pointed out to me:
1. Some maintainers like to extract their "uncodesigned tarball" inside the `output/` directory, resulting in the older `guix-attest` mistakenly attesting to the extracted contents
2. Maintainers whose GPG keys reside on an external smartcard often need to physically interact with the smartcard as a way to approve the signing operation, having one signature per platform means a lot of fidgeting
3. Maintainers wishing to sign on a separate machine now has the option of transferring only a subtree of `output/`, namely `output/*/SHA256SUMS.part`, in order to perform a signature (you may need to specify an `$OUTDIR_BASE` env var)
4. An `all.SHA256SUMS` file should be usable as the base `SHA256SUMS` in bitcoin core torrents and on the release server.
For those who sign on an separate machine than the one you do builds on, the following steps will work:
1. `env GUIX_SIGS_REPO=/home/achow101/guix.sigs SIGNER=achow101 NO_SIGN=1 ./contrib/guix/guix-attest`
2. Copy `/home/achow101/guix.sigs/<tag>/achow101` (which does not yet have signatures) to signing machine
3. Sign the `SHA256SUMS` files:
```bash
for i in "<path-to-achow101>/*.SHA256SUMS"; do
gpg --detach-sign --local-user "<your-key-here>" --armor --output "$i"{.asc,}
done
```
5. Upload `<path-to-achow101>` (now with signatures) to `guix.sigs`
-----
After this change, output directories will now include a `SHA256SUMS.part` fragment, created immediately after a successful build:
```

```
Meaning that they are valid `SHA256SUMS` files when `sha256sum --check`'d at the `guix-build-*/output` directory level
When `guix-attest` is invoked, these `SHA256SUMS.part` files are combined and sorted (by `-k2`, `LC_ALL=C`) to create:
1. `noncodesigned.SHA256SUMS` for a manifest of all non-codesigned outputs, and
3. `all.SHA256SUMS` for a manifest of all outputs including non-codesigned outputs
Then both files are signed, resulting in the following `guix.sigs` hierarchy:
```

Pull request description:
This PR is a proof of concept for using [LIEF](https://github.com/lief-project/LIEF) for the PE and MACHO symbol and security checks. It replaces our current approach of manually parsing the output of `objdump` & `otool`. If the consensus is that using LIEF is ok, then I also plan on replacing [pixie.py](https://github.com/bitcoin/bitcoin/blob/master/contrib/devtools/pixie.py), and using LIEF for all checks. LIEF for Linux is also currently blocked (on the next release, unless we want to build master) on one change for RISC-V that I [sent upstream](https://github.com/lief-project/LIEF/pull/562).
LIEF is seemingly well maintained, and is the basis for a number of other tools. It also has some very nice documentation; i.e the [Python API for ELF](https://lief.quarkslab.com/doc/latest/api/python/elf.html). It also has many builtins we can take advantage of. i.e [`is_pie`](https://lief.quarkslab.com/doc/latest/api/python/macho.html#lief.MachO.Binary.is_pie), [`has_nx`](https://lief.quarkslab.com/doc/latest/api/python/macho.html#lief.MachO.Binary.has_nx) etc. This means we can [consolidate some of our checks](9c5eeb5484). If/when end up using LIEF for lightning then we can consolidate further, and cleanup these scripts. i.e to not parse the binary inside the checks, but once at the start of the script.

This relatively easy change eliminates all runtime dependencies (except
for the kernel) for dmg, which is the only native build tool that gets
put in our output tarballs.
This allows much more flexibility when constructing the codesigning
environment, and is much more robust.
Bump glibc and linux-headers to match those of our Gitian counterparts.
We also require a glibc >= 2.28 for the test-symbol-check scripts to
work properly.
The default BASE-GCC-FOR-LIBC also has to be bumped since glibc 2.31
requires a gcc >= 6.2
The new time-machine commit is Guix v1.2.0 with a yet-unupstreamed patch
for NSIS.
A few important changes:
1. Guix switched back from using CPATH to C{,PLUS}_INCLUDE_PATH as the
way to indicate #include search paths.
2. GCC's library is now split into a separate output, whereas before it
was included in the default output. This means that our gcc toolchain
packages need to propagate that output.
3. A few package versions were bumped
When building nsis, if VERSION is not specified, it defaults to
cvs_version which is non-deterministic as it includes the current date.
This patches nsis to default to SOURCE_DATE_EPOCH if it exists so that
nsis is reproducible.
Upstream change: https://github.com/kichik/nsis/pull/13
The libtool unsorted 'find' determinism issue seemed to have been solved
in gcc-9's git: d41cd173e23ebea7c758644d6ad6e0fde1c2e3a6 or SVN: r262451
Furthermore, it seems that Ubuntu Focal 20.04 LTS is going to ship with
gcc 9 and mingw-w64 7, which will match what we have now.
-----
A note on this:
Careful observers will see that previously I stated that all released
versions of gcc were bootstrapped with a libtool 2.2.7a, meaning that
they all had the unsorted 'find' determinism issue first resolved in
libtool 2.2.7b.
However, I was mistaken, gcc's ltmain.sh CLAIMS it was generated by
libtool 2.2.7a, but it was in fact edited manually. It seems that gcc
maintains their own versions of ltmain.sh and libtool.m4, and only
sometimes backports patches from upstream.
Quite confusing.
Previously, Guix would produce a gcc which did not know to use the SSP
function from glibc, and required a gcc make flag for it to do so, in my
attempt to fix it upstream I realized that this is no longer the case.
This can be verified by performing a Guix build and doing
readelf -s ... | grep __stack_chk
to check that symbols are coming from glibc, and doing
readelf -d ... | grep NEEDED | grep ssp
to see that libssp.so is not being depended on
- Clearer and more accurate prose
- Pin `guix pull' to commit rather than branch
- Just use `use-module' instead of `define-module'
- Use `bash-minimal' instead of `bash'
- Remove unneeded `tcsh' from manifest
- Explicitly use `python-3.7'
- Add comments about how {native,cross}-toolchains are produced and
why
