> I think it should be possible if you make the relocation point to the object itself (which will have local linkage) and not the alias that you're creating.

It doesn't seem to work. Dynamic loader doesn't know anything about aliases - alias and aliasee can point to different memory locations if aliasee is preempted. 
Also let's say I have external declaration of variable `foo`. How do I know if `foo` is instrumented in another TU or not. If not then I think, I can't tag it's address
