Thanks, using LLVM 3.1 seems to have improved the siutation, but I'm 
running into a new error.

Here is the error I get when trying to build GHC 7.6.1 from 7.4.1

I get similar errors when building GHC 7.4.1 (patched with 
http://hackage.haskell.org/trac/ghc/attachment/ticket/5914/0001-add-support-for-ARM-hard-float-ABI-fixes-5914.patch).

Any of you encountered this problem before?
