release-cross: Add 64-bit big-endian POWER

[OPNA2608]

See #443234 (comment) for an overview of untested & known-failing builds. A decent amount of the tests work though, and should populate a good amount of cross-built derivations in the cache for easier testing of these targets.

Things done

• Built on platform:
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin
• Tested, as applicable:
  • NixOS tests in nixos/tests.
  • Package tests at passthru.tests.
  • Tests in lib/tests or pkgs/test for functions and "core" functionality.
• Ran nixpkgs-review on this PR. See nixpkgs-review usage.
• Tested basic functionality of all binary files, usually in ./result/bin/.
• Nixpkgs Release Notes
  • Package update: when the change is major or breaking.
• NixOS Release Notes
  • Module addition: when adding a new NixOS module.
  • Module update: when the change is significant.
• Fits CONTRIBUTING.md, pkgs/README.md, maintainers/README.md and other READMEs.

All:

• I think ghc*.hello should work, but I run out of storage building the GHCs together with everything else. Might give them a go separately, but not super urgent for me rn
• nixs should work after boehmgc: Fix support for multiple flags in CFLAGS_EXTRAS #441438 makes its way through staging to master

Glibc ELFv1:

• rustc¹, and by extension cargo, fail in a way that I'm unfamiliar with.
• mesa² fails due to rust-bindgen(?) giving clang a gnuabielfv*-containing target triplet, which it doesn't understand. This is fixed in the CC wrapper, so might need a similar fix somewhere else.

Glibc ELFv2:

• rustc currently can't parse the platform triplet… I think. Can crop the ABI part to just gnu like on glibc ELFv1, but then it builds ELFv1 objects and linking fails.
  There is a cfg.target_abi that would support setting elfv1 and elfv2, but I'm not sure if that can be done for the bootstrapping, or where/how one would set that. Will prolly just mark rustc as broken on big-endian glibc ELFv2 POWER, unless someone Rust-knowledgable can figure that out.

musl (ELFv2):

• Build failure: llvmPackages.compiler-rt-libc cross to ppc64-musl #443728, blocks everything relying on LLVM I think

[alexfmpe]

I think ghc*.hello should work

elfv1 builds and I can run it with $(nix-build -A qemu)/bin/qemu-ppc64, the other ones fail while building the cross compiling ghc

Looks similar to your Glibc ELFv2 issues above

ppc64 ELFv2 cross GHC might need https://gitlab.haskell.org/ghc/ghc/-/commit/ead75532c9dc915bfa9ebaef0ef5d148e793cc0a, or smth similar / older but related to it, applied/backported to the various source-built GHC versions that we support. Will see if I can find the time to look into that.

Maybe interesting to @minijackson as well?

[OPNA2608]

#462247 will fix pkgsCross.ppc64-elfv2.haskellPackages.hello, but needs some work still. Might also fix ppc64-musl, haven't tried that yet though. Checked, also fixes pkgsCross.ppc64-musl.haskellPackages.hello.

[minijackson]

There isn't any support guarantee for ppc64be, so I think this PR is perfectly fine as it is. I think the failing packages can be fixed on their own time, in subsequent PRs.

[OPNA2608]

@SuperSandro2000, anything against merging this? You asked for opinions on this in the #cross-compiling:nixos.org Matrix channel awhile ago, but I don't think anything ever came out of that.

[OPNA2608]

Okay well, I got asked to submit this in the first place, and I'm not aware of any restrictions that apply to adding cross-trunk jobset tests… And I'm somewhat actively working on fixing stuff.

Prolly fine to merge… If not, please revert. I'll blame the radio silence xP.
