In 2007, I view an upstream package that can't be compiled with -j4 to
be buggy.

It's a fair question as to whether MAKE_JOBS should default to off
unless MAKE_JOBS_SAFE=yes, but so far we aren't headed that way.

It looks like firefox builds with MAKE_JOBS, or at least make show-all
leads me to think that.
Granted, it's hard to prove that it is safe in all cases, but that's the
kind of package where I'd expect the upstream folks to be doing parallel
builds themselves.
