One slightly annoying thing is that (e)glibc isn't buildable with gold
because the linker scripts don't work. So a little bit of patching is
going to be needed to have it use ld.bfd there. There might be some
other packages with similar issues but I haven't come across any yet.
I think something like this is probably what's required for that.
