trouble building ghc-7.4 on Fedora 18 (devel) ARM

I've just attached my fix for hard-float ABI build failure on GHC HEAD 
to the #5914.

I would be more than glad if you can attempt to merge it to 7.4.x you 
are packaging and test if it works for you on both soft and hard float 
ABI. Hard seems to be preferred these days at least on Linux...

If you keep me posted about this either by email or by adding info to 
bug above, I would really appreciate it.

Once you verify the fix is working on 7.4.x I'll push it for inclusion 
on HEAD even I'm not able to bootstrap it fully (see #6043) and from 
HEAD it will be merged hopefully to 7.4.x branch to easy your packaging
