haskellPackages.c2hsc: apply patchto find gcc

[teto]

...used in tests.

Fix is upstream but there has been no sign of release for the past 6
months, fixes #63764.

I might need to remove it from the list of borken packages, is that correct ?

Motivation for this change

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Ensured that relevant documentation is up to date
• Fits CONTRIBUTING.md.

Could you rebase this on the haskell-updates branch?

Also, you're correct. c2hsc needs to be removed from the broken packages section in pkgs/development/haskell-modules/configuration-hackage2nix.yaml.

Hmm, I appear to be getting a different hash for this:

$ nix-build -A haskellPackages.c2hsc --arg config '{allowBroken=true;}'
these derivations will be built:
