Subject: [PATCH] haskell.packages.ghcHEAD: use llvm 10

As per GHC's documentation:
https://gitlab.haskell.org/ghc/ghc/-/wikis/commentary/compiler/backends/llvm/installing#llvm-support

This configuration file is probably outdated in major other ways. We
should most likely copy over stuff from the GHC 9.0.x config file and
adjust new specifics, but I don't have the time at the moment.
