[Mageia-sysadm] Revert ghc to previous stable version

[Pierre-Malo Deniélou]

Dear all,

I pushed ghc-7.6.1 a bit too soon, and I know realise that having the
stable 7.4.2 version is better for Mageia 3. Can the sysadm team remove
ghc-7.6.1, ghc-doc-7.6.1 and ghc-prof-7.6.1 from the mirrors and replace
it with the mga2 version (7.0.4)?
I will then revert the svn and update to 7.4.2.

Thanks,
