Now that our Guix builds are performed on glibc 2.24 and 2.27 (RISCV),
we no-longer need to pass the --enable-glibc-back-compat option.
Replace it with --disable-threadlocal, to prevent the usage of symbols
from glibc 2.18.
None of the binaries produced required symbols later than 2.17, and 2.27
(RISCV).
Our 'bitcoin-linux-g++' definition better integrates with our depends
system than the stock linux-g++-64 definition.
This fixes a bug whereby Guix builds on x86_64 for x86_64 did not
produce a QMinimalIntegrationPlugin and led to bitcoin-qt not being
built.

Pull request description:
There seems to be some corner cases that can be hit when guix scripts unexpectedly fail in the middle of operation, see: https://gnusha.org/bitcoin-builds/2021-05-24.log
- Perform an early disk space check for `guix-build`
- Overwrite existing output directory after a successful build (the existing one might be malformed), and cleanup output directory if the `mv` somehow fails

a58868d201 build: Makes rcc output always deterministic (Hennadii Stepanov)
Pull request description:
The Qt Resource Compiler ([rcc](https://doc.qt.io/qt-5/rcc.html)) has a command-line option `--format-version` which has the [default value](https://code.qt.io/cgit/qt/qtbase.git/tree/src/tools/rcc/main.cpp?h=5.12.10#n172) 2.
The only difference from `--format-version 1` is adding a [last modified timestamp](https://code.qt.io/cgit/qt/qtbase.git/tree/src/tools/rcc/rcc.cpp?h=5.12.10#n207) to the output file ([credits](https://github.com/bitcoin/bitcoin/pull/21654#issuecomment-819198228) to **fanquake**). That, in turn, forces us to use `QT_RCC_SOURCE_DATE_OVERRIDE=1` to get deterministic builds (#13732).
This change makes rcc output always deterministic by using `--format-version 1` option that makes usage of the
`QT_RCC_SOURCE_DATE_OVERRIDE` needless.

6f6bb3ebc7 test: fix file permissions on various scripts (windsok)
Pull request description:
Adds a new python linter test which tests for correct filenames and file permissions in the repository.
Replaces the existing tests in the `test/lint/lint-filenames.sh` and `test/lint/lint-shebang.sh` linter tests, as well as adding some new and increased testing. This increased coverage is intended to catch issues such as in #21728 and https://github.com/bitcoin/bitcoin/pull/16807/files#r345547050
Summary of tests:
* Checks every file in the repository against an allowed regexp to make sure only lowercase or uppercase alphanumerics (a-zA-Z0-9), underscores (_), hyphens (-), at (@) and dots (.) are used in repository filenames.
* Checks only source files (*.cpp, *.h, *.py, *.sh) against a stricter allowed regexp to make sure only lowercase alphanumerics (a-z0-9), underscores (_), hyphens (-) and dots (.) are used in source code filenames. Additionally there is an exception regexp for directories or files which are excepted from matching this regexp (This should replicate the existing `test/lint/lint-filenames.sh` test)
* Checks all files in the repository match an allowed executable or non-executable file permission octal. Additionally checks that for executable files, the file contains a shebang line.
* Checks that for executable `.py` and `.sh` files, the shebang line used matches an allowable list of shebangs (This should replicate the existing `test/lint/lint-shebang.sh` test)
* Checks every file that contains a shebang line to ensure it has an executable permission
Additionally updates the permissions on various files to comply with the new tests.

We already attest to the relevant dist-archive in inputs.SHA256SUMS,
which is recorded at build-time.
We use a SKIPATTEST.TAG file to indicate output directories which do not
require attestation (much like the CACHEDIR.TAG specification).
Generally, it's better to have build scripts declare properties of
directories instead of introducing name-based special cases in attest
scripts since build scripts have a more detailed context of what is
going on.
At build/codesigning-time, hash build inputs and output the digest to
${OUTDIR}/inputs.SHA256SUMS, which gets included in the final SHA256SUMS
constructed by guix-attest.
Example final SHA256SUMS:

While files are being output to $OUTDIR, it will be under
${DISTSRC}/output, and only when everything is done, will
${DISTSRC}/output be moved to the actual $OUTDIR.
This makes it so that a Ctrl-C in the middle of a build is less likely
to result in a partially-constructed $OUTDIR. In fact, if I understand
correctly, if $OUTDIR and $DISTSRC reside on the same filesystem, the
move (rename) is likely atomic.
Also, since the "working $OUTDIR" is under ${DISTSRC}/output, it will be
cleaned properly by the guix-clean script.

guix: Record precious directories and add guix-clean
Many users have reported problems that stem from having an unclean
working tree. To that end, I've written a guix-clean script which should
help reset the working tree while respecting user-specified precious
directories.
Precious directories, such as:
- SOURCES_PATH
- BASE_CACHE
- SDK_PATH
- OUTDIR
Should be preserved when cleaning the working tree, and are thus
recorded in ./contrib/guix/var/precious_dirs.
The ./contrib/guix/guix-clean script is able to parse that file and make
sure to avoid them when cleaning out the working tree.

By registering the container profiles as garbage collector roots, it
will prevent `guix gc` from garbage collecting derivations which our
container needs and inconvieniencing the user with a rebuild.

The ./contrib/guix/guix-clean script is able to parse that file and make

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.
./windeploy is a "working directory", and therefore belongs inside
distsrc-*. Many people have noticed their Guix builds failing after
hours simply because they did not remove windeploy (but did remove the
distsrc-* directories).
In Guix, there are two flags for controlling parallelism:
Note: When I say "derivation," think "package"
--cores=n
- controls the number of CPU cores to build each derivation. This is
the value passed to `make`'s `--jobs=` flag.
- defaults to 0: as many cores as is available
--max-jobs=n
- controls how many derivations can be built in parallel
- defaults to 1
Therefore, if set --max-jobs=$MAX_JOBS and don't set --cores, Guix could
theoretically spin up $MAX_JOBS * $(nproc) number of threads, and that's
no good.
So we could either default to --cores=1, --max-jobs=$MAX_JOBS
- Pro: --cores=1 means that `make` will be invoked with `-j1`,
avoiding problems with package whose build systems and test
suites break when running multi-threaded.
- Con: There will be times when only 1 or 2 derivations can be built
at a time, because the rest of the dependency graph all depend
on those 1 or 2 derivations. During these times, the machine
will be severely under-utilized.
or --cores=$MAX_JOBS, --max-jobs=1
- Pro: We don't encounter prolonged periods of
severe under-utilization mentioned above.
- Con: Many packages' build systems and test suites break when running
multi-threaded.
or --cores=1, --max-jobs=1 and let the user override with

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
Any -O argument will enable optimizations in GNU ld. We can use -O2
here, as this matches our compile flags. Note that this would also
enable additional optimizations if using the lld or gold linkers,
when compared to -O0.
This is no longer needed after 3bef7c22 in the mingw-w64 git repository,
which is first included in mingw-w64 v7.0.0.
As of the previous bump to our Guix time machine, we now use mingw-w64
v7.0.0.
