setup instructions: ghc 7.10

[cocreature]

setup/SETUP.md mentions that one should get a patched version of ghc from git@github.com:fpco/ghc but that repo does either not exist or is not public.

[snoyberg]

Those instructions are out-of-date actually, a custom GHC is no longer necessary (all patches have been merged upstream). Would you be able to send a PR to update the docs?

[cocreature]

I can try to do that, but I need to figure out how to get bytestring-trie to work first. I don't want to submit instructions I couldn't reproduce myself.

(I've emailed that to the author of bytestring-trie on Jan 20, but no reply.)

@edsko Thanks, that did the trick. I was trying to build upon darks head which has some changes regarding ghc 7.10 but didn't want to built for me at all. I'll make a pr to update the setup instructions later, if you want to do it yourself, that's obvously also fine with me.
