This is not going to work now IMHO, since at least LlvmCodeGen/Ppr.hs 
provides platform specific module layout specification. As current GHC 
does not support cross-compilation *yet* (see Stephen's work on mailing 
list), then you are basically supplying LLVM llc with x86 specific data 
layout attempting to compile for ARM...
