Allow one to specify a second parameter to the machine line. This

allows us to specify the machine_arch as well as machine.  If
specified then a second link will be made, similar to machine, from
$MACHINE_ARCH to $S/$MACHINE_ARCH/include.

This is for ports where MACHINE != MACHINE_ARCH (pc98 today, others in
the future?).
