See docs.
Follow-up work:
- Existing packages should be converted
- `defaultPkgConfigPackages` should assert on `meta.pkgConfigModules`
and let `tests.pkg-config` alone test the build results.

platform.uname.processor seems to be what we want in many more cases
than what we were using before — it does the right thing for aarch64,
x86_64, riscv32, riscv64, mips, mips64, powerpc, and powerpc64 (the
latter three of which were broken before).
This fixes cross-compilation of systemd for PowerPC/POWER platforms.
FreeBSD doesn't use LLVM's cxxabi implementation, for backwards
compatibility reasons. Software expects the libcxxrt API when
building on FreeBSD. This fixes the build of
pkgsCross.x86_64-freebsd.boost.
Some other packages, for example ruby gems via buildRubyGem, use a
variable called "type" internally, which is overwritten here and
causes failures like:
failure: $gempkg path unspecified

`builtins.baseNameOf` retains any string context, causing the test

to know what the dynamicLinker is called, but we don't need it to be
present in store.

After https://github.com/NixOS/nixpkgs/pull/209054 we started moving
libstdc++.so out of default glibc's paths. This exposed bootstrap
tools build failure as:
$ nix build --no-link -f ./pkgs/stdenv/linux/make-bootstrap-tools.nix
...
>
.../bin/bar: error while loading shared libraries: libstdc++.so.6:
cannot open shared object file: No such file or directory
Note that bootstrap itself did not break. The change only expands
handcrafted `-rpath` entries.
The stdenv bootstrap creates several wrappers around binutils, and
gives them the exact same drvName as the binutils package itself.
These wrappers cost almost nothing to create (they are just file
copies and patchelf runs, not builds), so we should distinguish them
from expensive binutils builds with a unique pname. This commit
does that.
`hasUnsupportedPlatform` was not updated with #37395, so it does not
understand attrsets in `meta.[bad]platforms`. In particular,
attrsets in `meta.badPlatforms` will "fail open" and be ignored.
Let's use `lib.meta.availableOn` instead of duplicating its logic.
Thanks to @alyssais for [noticing][1].

Right now we build gettext several times during the bootstrap.
Gettext's build process is "embarrassingly serial", so avoiding
rebuilding it speeds things up considerably.
otherwise the build just fails with 'make: *** No rule to make target 'install'. Stop.'
and update buildPhase message
i don't know if the 'makefile may have been created in buildPhase' is
true but i guess it might be possible
This change allows building new gcc during bootstrap without fear of
pulling in outdated libstdc++.so after g++ switched from bootstrapTools
to freshly built g++.
Noticed when tried to add early bootstrap stage to rebuild `gcc` before
`glibc` is fully untangled from `bootstrapTools` as a failure to built
`binutils`:
ld: dwp.o: in function `__gnu_cxx::new_allocator<gold::Dwp_output_file::Contribution>::allocate(unsigned long, void const*)':
/nix/store/...-gcc-11.3.0/include/c++/11.3.0/ext/new_allocator.h:116: undefined reference to `std::__throw_bad_array_new_length()'
The change survives existing bootstrap and unblockes early `gcc` bootstrap.
Just a few comments added:
- added a few one-liners to explore which tools are rebuilt at each
stdenv iteration during bootstrap
- explicitly listed available toolchains and their sources for on each
bootstrap step: glibc, binutils, gcc, coreutils.
- added mention of static libraries linked into gcc

The documentation for `meta.sourceProvenance` in
`doc/stdenv/meta.chapter.md` says: "the `meta.sourceProvenance`
attribute should be a list containing one or more value..."
Let's update check-meta.nix to require that `meta.sourceProvenance` is
a list, as the documentation says, rather than a single element.
Adding two extra keystrokes `[` and `]` when filling out this field is
an insignificant burden for package authors, and being able to assume
that the `meta.sourceProvenance` field is always a list greatly
simplifies any code that acts on the value of this field.
Since `meta.sourceProvenance` was just merged a few hours ago now is
the easiest time to fix this: nobody is using the feature yet.
