[30721] use_parallel_build / portfile-phase.7.xml

[Weissmann Markus]

I've just added a way to automatically set the number of build jobs  
(if desired):
If the number of build jobs is set to "0" (in the config file), the  
number of jobs is set to the number of cores.

This works only on Mac OS X (and FreeBSD -- though untested).
