[arch-general] GHC 7.6.1 now in [extra]

[Thomas Dziedzic]

Hey everyone!

It's that time again for arch to get the latest ghc!
GHC 7.6.1 comes with a bunch of new and exciting features:
http://www.haskell.org/ghc/docs/7.6.1/html/users_guide/release-7-6-1.html

It took just over a month to do the full rebuild because of the
amount of patching and coordination with upstream we had to do.

I would like to thank everyone who worked on this rebuild!

Cheers!
