Initial checkin of the toolchain_lookup() rule for expressing explicit dependencies on Make variables and toolchains.

I'm not particularly happy with the fact that it needs to depend on every configuration fragment that defines Make variables, but this seemed more reasonable than having a rule class for every fragment, just to have a lonely single rule of that class.
