I now have another failure to build with llvm3.6 (release) not sure if it's an
LLVM or flag change. It would build with "-fpermissive". See in-line.

I get a failure to convert from int to LLVMLinkerMode from the 3rd
argument here. The constant '0' needs to be cast to LLVMLinkerMode to
keep LLVMLinkModules() happy since it doesn't accept an int argument.
