Don't create dynamic relocations to ro segments. These would just crash at runtime. If we ever decide to support rw text segments this should make it easier to implement as there is now a single point where we notice the problem. I have tested this with a freebsd buildworld. It found a non pic assembly file being linked into a .so,. With that fixed, buildworld finished. llvm-svn: 268149 2016-04-30 09:15:17 +08:00			`// REQUIRES: x86`
