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.

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.
Format all Nix files using the officially approved formatter,
making the CI check introduced in the previous commit succeed:
nix-build ci -A fmt.check
This is the next step of the of the [implementation](https://github.com/NixOS/nixfmt/issues/153)
of the accepted [RFC 166](https://github.com/NixOS/rfcs/pull/166).
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).
If you run into any problems regarding any of this, please reach out to the
[formatting team](https://nixos.org/community/teams/formatting/) by
pinging @NixOS/nix-formatting.
Add a new `aarch64-freebsd` double and example system,
then fix include and libc to work.
This is enough to build packages like `hello`,
either static or dynamic.
This is useful for testing nix FreeBSD on a Raspberry Pi.
`For android 'sdkVer' has been renamed to 'androidSdkVersion'`
While doing the above rename I forgot to consider if there were still
darwin platforms in `lib.systems.examples` using `sdkVer`
These still fail eval, but that happened before the renaming too.
`error: Unsupported sdk: 14.3`
Those attrs have been renamed and throwing is the best way to show it,
if we only warned then the user would only get an error like this `error: Unsupported sdk: 33`
from `pkgs/top-level/darwin-packages.nix`.
If someone wants to support multiple NixOS versions then they can simply
set both attrs. (`!args ? androidSdkVersion` is for that)
`sdkVer` conflicts with the old `sdkVer`(now `darwinSdkVersion` but that still uses `sdkVer` if set) used by darwin
This shouldn't be an issue but due to `pkgs/development/interpreters/python/cpython/default.nix`
running `lib.filterAttrs (n: v: ! lib.isDerivation v && n != "passthruFun")` on it's inputs (2 of them are darwin only)
the `throw "Unsupported sdk...` in `pkgs/top-level/darwin-packages.nix` will be triggered.
After this change `pkgsCross.armv7a-android-prebuilt.python3.pythonOnBuildForHost` won't fail with
`error: Unsupported sdk: 33`
Issue was bisected to 3cb23cec23
`rustc.config` is called `rust.rustcTarget` now, and
`{rustc -> rust}.platform`.
This is the new way (tm), and is preferred since
https://github.com/NixOS/nixpkgs/pull/271707 -
though the documentation still is outdated, and some expressions in
nixpkgs were using the old interface.
This updates both.
We have several cross-compilation bugs that show up if
hostPlatform!=buildPlatform yet
hostPlatform.config==buildPlatform.config.
These bugs have appeared and disappeared as we've fiddled with the
definition of equality for platform objects. This commit adds a
clear-cut case where they are *not* equal and never will be, so we
can test it.
The Minimalist Gnu for Windows distribution comes with support for
the traditional msvcrt libc, as well as ucrt64 libc. The latter
being the newer universal compiler runtime. We follow the msys2
environment naming convention[1]:
| name | toolchain | arch | libc | libc++ |
|------------|-----------|---------|--------|-----------|
| mingw32 | gcc | i686 | msvcrt | libstdc++ |
| mingw64 | gcc | x86_64 | msvcrt | libstdc++ |
| ucrt64 | gcc | x86_64 | ucrt | libstdc++ |
| clang32 | llvm | i686 | ucrt | libc++ |
| clang64 | llvm | x86_64 | ucrt | libc++ |
| clangarm64 | llvm | aarch64 | ucrt | libc++ |
For now nixpkgs only supports the first three with this commit.

Add support for Nvidia's Bluefield 2 plattform as a compilation
target. There exists a version with and without crypto support,
while the crypto supported version is the most common one.
Support for the non-crypto version can be easily added in the future,
if needed.
For a datasheet of the hardware, see:

- Christmas is over!
- Upstream has changed the name of the target triplet used for the JS
backend from js-unknown-ghcjs to javascript-unknown-ghcjs, since Cabal
calls the architecture "javascript":
6636b67023
Since the triplet is made up anyways, i.e. autoconf does not support
it and Rust uses different triplets for its emscripten backends, we'll
just change it as well.
- Upstream fixed the problem with ar(1) being invoked incorrectly by stage0:

A tricky thing about FreeBSD is that there is no stable ABI across
versions. That means that putting in the version as part of the config
string is paramount.
We have a parsed represenation that separates name versus version to
accomplish this. We include FreeBSD versions 12 and 13 to demonstrate
how it works.
In Nixpkgs, we assume that the "config" field is a canonicalized GNU
triple. I noticed that non-canonical values were being used here,
because the pkgsCross.mips64el-linux-gnu triples did not contain the
vendor field, but the pkgsCross.mips64el-linux-gnu.pkgsStatic did.
Here, I've run all the MIPS triples in lib.systems.examples through
config.sub to canonicalize them. I think this will avoid nasty
surprises in future.
Tested by building Nix and the bootstrap files for
pkgsCross.mips64el-linux-gnu.
This has been deprecated for a long time, and it's doubtful it had any
users to start with. And having an undisablable warning when
enumarating platforms is not good.
These servers apparently no longer exist, since September 2, 2021[1].
If somebody needs this for non-Scaleway machines, they should suggest
its reintroduction with a different name.
