I am not sure if it is the correct solution, but the attached patch
fixes the problem.
The build now fails when linking lto:
relocation R_X86_64_32 against `(anonymous namespace)::EmittedInsts'

Your solution is correct, in that it will work and follows with the current ifdef approach. I applied this patch though, which doesn't use the ifdefs, hopefully it is more robust:

Please lemme know if it works.

It does. Thanks.

I believe that code compiled without -fpic is going into a DSO. This
creates text relocations that are not supported on linux/amd64
(http://people.redhat.com/drepper/dsohowto.pdf).

Okay, Anton just committed a patch to exclude liblto on non-darwin platforms for the time being. That should fix it.
