In the ymakefile in gnuemacs 18.54, cpp takes the definition of
MAKE_PARALLEL (if there is one) and places it into the xmakefile
to allow the native make to parallelize the compile.

On a Sequent (Symmetry, Dynix 3.0.12), the MAKE_PARALLEL variable is
defined to be '&', as per the /bin/make on that machine.  But I use
gnu make (3.54.5), which does not understand the '&', and the build process
promptly dies.

Is there some clever way to determine whether or not the parallel build
process goes on or not?  Perhaps for v19, there could be a better way of
making this an option.

I put a blank #define MAKE_PARALLEL just before the test in ymakefile, just
to clear the value.

Maybe this should go into the PROBLEMS file, referenced by parallel compile
and GNU make.
