With "using GNU ld" I mean configuring with --with-plugin-ld=ld.bfd (or omitting that configure option). I'm CCing a gold expert, maybe he can shed some light on that error. I suppose all object files _are_ built with -fPIC (eventually LTO takes some symbols local by making them have hidden visibility - can that cause issues?).
