Comment (by dfeuer):

 Also, are you passing `-fPIC` specifically somewhere? I'm only asking
 these picky questions because if this is LLVM-only, it seems awfully
 likely to be something horrible going wrong generating code for the stage
 1 compiler. I don't think we really do anything LLVM specific in the
 specializer or the simplifier, although I could be missing something.
