binutils/binutils: simplify gold dependencies

In preparation of adding a new kernel-type, Yann D. came up
with a change in semantic on binutils/gold availability.

So far, it was architectures' responsibility to declare that
they did support binutils/gold or not. It makes much more sense
that binutils/gold declares its own availability depending on
the current architecture; after all, architectures have no way
to know wether gold supports them, while gold does know it.
