I use a very similar aproach to mrg's (a wrapper script around build.sh
that sets -M depending on the requested arch)

This is a plus!

The nbmake-${arch} wrapper remembers it, so no need to keep the variable
around afterwards.

Anyway, I am not sure I understood what you are trying to do. We could
modify the default objdir (if no -O and no -M options are given to build.sh)
to fully include ${MACHINE_ARCH} without patching make, can't we?
