I've tried modifying offload_handle_link_vars but that spot doesn't catch

Why doesn't catch it? Is the variable created only post-IPA?
I'd think that it should have been created before IPA, streamed and
therefore I don't understand why you don't see it after streaming LTO in.
On closer inspection it does, in fact, catch it as you'd expect, but
then the variable is no longer marked public when it gets to
pass_omp_target_link::execute, so something somewhere is resetting it.
More investigation is needed....
