portconf and pkgtools.conf are files that are used by tools external to 
the base ports system (portmaster and portupgrade). The ports makefiles 
do not read them. The traditional place to put port configuration info 
is /etc/make.conf.

Since using the whitelist is not intended to be an officially supported 
feature, but only exists to make life a bit easier for people who are 
debugging the ports or willing to experiment, I expect that on 99% of 
FreeBSD systems, the whitelist will not be specified at all. I 
therefore see no reason to increase the complexity of the whitelist 
parsing code by introducing non-make-compatible syntax.

The patch used the name PARALLEL in a previous incarnation; MAKE_JOBS 
was chosen to avoid misunderstandings and name conflicts with ongoing 
work to allow several ports to be built in parallel, independently of 
each other. MAKE_JOBS might not have as nice a ring to it, but the 
intention is clearer.
