Good point.

I was mainly considering x86_64 here. It might be safest to limit the 
use of gold to this platform. From the developer point of view, it's the 
one that counts most.

But even if I change this to only use gold on x86_64, I'd still like to 
bump the binutils version globally. There's no good way to express 
different version requirements on different platforms for the same 
toolchain. Do you see a problem with that?
