description:
Back in 1993 ${MACHINE} was a unique way to define objdirs for
every platform. Thus setting OBJMACHINE, allowed one to keep
in-tree objdirs with multiple builds. With the advent of evb*, this
has become impossible until now. Introduce OBJMACHINE_ARCH that
adds ${MACHINE_ARCH} to the objdir so that we have unique objdirs
per build again. Until we restructure things to that this is not
necessary, it is the simplest fix.
