While using the assembler from llvm should be straight forward enough, assuming
Apple didn't push its obsoleting of i386 changes upstream, the linker would be
a tricker issue since the llvm lld code hasn't been kept up on the Darwin side
for quite some time.

I pinged Jeremy to see if he can nudge that along.
