rocmPackages_5: pin stdenv to GCC 12

[Madouura]

Description of changes

Lazy fix for the linked issue that I have not tested, as I do not have much time currently.
Only merge once #268097 is merged.

There is a lot more I can do here, there was a rocmPackages rework I was working on, which I think I accidentally just killed with this branch thankfully github is smart (https://github.com/Madouura/nixpkgs/tree/dev/rocm-rework). Oh well. Any further improvements/nitpicks should go to that, this is just a quick fix.

Fixes: #271943

@amjoseph-nixpkgs can we just cherry-pick this into your PR?

Testing now...

Could you switch the base branch to staging? Since the gcc13 upgrade is going to staging there isn't really any need for this on master.

Once my build finishes I'll merge this and rebase #268097

Thanks, I got build failures in rocm-llvm-libc but I think the first commit in this PR fixes it:

• rocmPackages_5.llvm.base: override stdenv, set gccForLibs #272190

The second commit in that PR might not be necessary; checking that right now.

This is 99% of the solution; the other 1% is in

• rocmPackages_5.llvm.base: override stdenv, set gccForLibs #272190

Will merge as soon as ofborg finishes CI.

Rebased in order to make ofborg re-eval.

I have built both of these derivations locally:

/nix/store/bgj8mchi88pzgs9c24xb0kivlmglfmhp-nix-2.3.17.drv
/nix/store/c076ydrflsfx4p849f810mmidpzi6yq2-nixpkgs-lib-tests.drv

The first derivation is the one that @ofborg choked on. The second derivation is eval-lib-tests for this PR.

Therefore, I am going to merge this.

Good thing we can run CT locally!
