Turns out we do need to do bootstrapping of MACHINE_CPU here: make(1) won't
set the variable until you rebuild it, and the alternative is to be stuck
playing games with ``.if defined(MACHINE_CPU) && ... '' for all eternity.
We now set up the reasonable default for i386 and alpha here -- given this
it probably makes sense to remove the corresponding code from make(1).
