	directly on the mac.  This is very early, doesn't support relocations and
has a terrible hack to avoid .machine from being printed, but despite
that it generates an bitwise-identical-to-cctools .o file for stuff like 
this:
  define i32 @test() nounwind { ret i32 42 }
I don't plan to continue pushing this forward, but if anyone else was
interested in doing it, it should be really straight-forward.
