Don't confuse poudriere's PARALLEL_JOBS with the number of jobs for
building a single port. Poudriere defaults to always use a single job
for a single port, you can override this with ALLOW_MAKE_JOBS=yes
globally, or with ALLOW_MAKE_JOBS_PACKAGES for individual ports.

PARALLEL_JOBS just tells how many ports are built in parallel.

As long as this isn't available yet, there's always the old trick
checking .CURDIR like for this example:

.if ${.CURDIR:M*/devel/llvm*}
DISABLE_MAKE_JOBS=yes
.endif

This works because make.conf is just included. But see above why this
shouldn't be needed to control the make jobs when using poudriere.
