I'm going for just a comprehensive NACK. If they fix clang so that at
least the thunk symbols __x86_indirect_thunk_\reg are compatible, then
we could tolerate command line differences. Otherwise, just no.

Unless you really fancy trying to do some kind of alias hack in modules
so that they link to the external thunk by its proper name, even when
built with clang? I reserve the right to hate that too.
