[haskell-llvm] Make sure you include the correct TargetSelect.h and that InitializeAllTargetMCs() is being invoked!

I have copied the changed lines from your patch manually into my llvm 
working copy. I wondered why you used a #def and did not write just:

foreign import ccall unsafe "LLVMInitializeNativeTarget" initializeNativeTarget :: IO CUInt


But it does not matter, I still get the following error, when running 
Align_dyn.exe:

Align_dyn.exe: LLVMTargetMachine.cpp:123: 
llvm::LLVMTargetMachine::LLVMTargetMachine(const llvm::Target&, 
llvm::StringRef, llvm::StringRef, llvm::StringRef, llvm::Reloc::Model, 
llvm::CodeModel::Model): Assertion `AsmInfo && "MCAsmInfo not 
initialized." "Make sure you include the correct TargetSelect.h" "and that 
InitializeAllTargetMCs() is being invoked!"' failed.
