Fedora ghc-7.10.1 repo

Hi, It is a bit later than I wanted but I have prepared a Fedora Copr repo for ghc-7.10.1. https://copr.fedoraproject.org/coprs/petersen/ghc-7.10.1/ (note the EPEL7 and F20 builds are currently quick builds and the F21+ builds are perf builds) I will probably add a cabal-install build soon. Let me know if you find any problems or if it is useful. :) Jens
