Adds --enable-checking=release and --disable-{libgomp,libquadmath,libitm,libvtv,libssp,libatomic,libstdcxx-pch,nls} to all GCCs (those runtime libs are unused by the stdenv); switches gcc-4.6{,cxx} to install-strip; adds --disable-nls to binutils and coreutils; adds --disable-test-modules --without-ensurepip --without-static-libpython to python.
Bootstrap self-size 1.45 GB -> 940 MB; gcc46-cxx -14%, glibc -10%, gcc-latest -6% wall on the heavy builds.
(make -j was tried on tcc-built derivations and broke them silently; NOTE comments left in the affected files so this isn't re-attempted.)
We now build tinycc-musl through an intermediate stage.
BEFORE:
tinycc-mes (links to mes-libc) -> musl -> tinycc-musl (links to musl)
NOW:
tinycc-mes (links to mes-libc) -> musl-intermediate
-> tinycc-musl-intermediate -> musl -> tinycc-musl
This fixes some issues with handling floating-point numbers:
certain float routines are not implemented are not implemented in mes-libc,
which would cause a miscompiled musl in the old approach.
Certain unnecessary musl patches are dropped. It is especially important to
remove the weak symbol patch, which in fact breaks the build.
tinycc-musl is upgraded to the latest "mob" version, with a couple bugfixes.
The upstream version of this patch has been commented out
since 913e70d77b, due to
error: implicit declaration of function '__stdio_exit'
Revived this approach by updating the patch to forward declare.
This commit was created by a combination of scripts and tools:
- an ast-grep script to prefix things in meta with `lib.`,
- a modified nixf-diagnose / nixf combination to remove unused `with
lib;`, and
- regular nixfmt.

After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.
