Previous revision didn't fix all cases. For example,

testing for variables that are always defined (e.g.,
"make -V CC") would still print a false warning.  Fix
this by only passing a submake the MAKEOBJDIRPREFIX=*
argument if it was present.  As a result, we loose
the check for -DMAKEOBJDIRPREFIX, or an esoteric
"MAKEOBJDIRPREFIX = foo" (with embedded spaces), but
these are unorthodox enough to not care about them.

The make(1) bug mentioned in the previous revision
was just fixed in make/main.c,v 1.109.
