llvm-hs is broken on darwin. This PR fixes it.

There is a thread on discourse where I investigated why it was broken:

https://discourse.nixos.org/t/how-to-get-llvm-hs-building-on-macosx-in-nixpkgs/4780

@ElvishJerricco suggested a simple fix, and in trying it I came up with something relatively simple that worked.

Motivation for this change

llvm-hs's Setup.hs file tries to add the lib/ directory from LLVM8 to the DYLD_LIBRARY_PATH environment variable. This messes up clang when called from GHC, probably because clang is version 7, but we are using LLVM8.

This PR patches the Setup.hs file to not modify the DYLD_LIBRARY_PATH environment variable.

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 nix-review --run "nix-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.
