Rust does not know how to parse "gnuabielfv{1,2}", so simplify those down to just "gnu".
This obsoletes the manual rustcTarget fix in the ppc64-elfv1 example.
The old cygwin support used -pc-windows-cygnus as the config. This is
supported by LLVM, but not by GNU. This will change it to -pc-cygwin,
which is more generally supported.
Because the kernel is now 'cygwin' rather than 'windows', isWindows will
return false. There are lots of different reasons isWindows is used in
nixpkgs, but in my experience they often have to do with posix
compatibility and don't apply to cygwin.

this architecture mapping is used broadly in the node ecosystem.
an assortment of tools and hooks, like buildNpmPackage or
pnpm.configHook, will benefit from reusing these values. placing them in
stdenv makes sense because (1) several of these tools don't currently
depend on nodejs, and may even be available where nodejs is not and (2)
`stdenv.{build,host,target}Platform` seems to be less error-prone than
`pkgs*.nodejs.{os,arch}` -- especially for setup hooks where the offsets
are shifted.
ELFv1 is the historically better supported one on glibc, ELFv2 seems to have some issues with our toolchain.
Restore the option to pick the ABI with pkgsCross.
qemu architecture names are fixed — we're using uname here just
because it's more likely to be correct than CPU name (see e.g. POWER).
This means that aarch64 is always called aarch64, even on Darwin where
uname reports arm64.
Fixes: 61582c7043 ("lib/systems: use Darwin architecture names for `config` and `uname`")

This commit will lead to merge conflicts for a number of PRs,
up to an estimated ~1100 (~33%) among the PRs with activity in the past 2
months, but that should be lower than what it would be without the previous
[partial treewide format](https://github.com/NixOS/nixpkgs/pull/322537).
Merge conflicts caused by this commit can now automatically be resolved while rebasing using the
[auto-rebase script](8616af08d9/maintainers/scripts/auto-rebase).
