The limitation seems to be that BUILD is not defined properly in the 
context of a .mk file until another .mk has installed config.guess. 
Before 0c474184b1b9 gcc.mk did not use BUILD.

I wasn't sure if the general advice to supply --build when --target is 
supplied would apply to binutils. If not, maybe we should remove the 
--build there as well as the comment about not being able to use BUILD. 
What do you think?
