Just to be clear: make doesn't ensure that the jobs it starts are run on
different CPU's.  That's up to the operating system to decide.

GNU make can be built with the Customs package that's distributed with
pmake.  This will give you the ability to do distributed builds (builds
on more than one system).  See the README.customs file in the GNU make

There are also patches floating around to integrate PVM (Parallel
Virtual Machine) support into GNU make; if you have a PVM environment
then you can run GNU make within it to get distributed builds.  See:
