[Nix-dev] Use GHC 7.10.1 as default Haskell compiler in nixpkgs

[Peter Simons]

Hi Mateusz,

I created pull request [1] to experiment with the new version. Test
builds are running at [2]. [3] shows how 7.10.1 compares to 7.8.4 in
terms of ability to compile the Hackage package set.

Best regards,
Peter
