>Description:

	Some large applications in The Ports Collection are known to build
	fine in a parallel fashion with -jN.  GCC is one example of such a
	port.

	 Below is a rough diff that allows a well tested port to set
	'USE_MAKE_J' to cause $MAKE to run with -jN.

	(I thought I had filed this in a PR previously, but I cannot
	find it searching http://bugs.freebsd.org)

>How-To-Repeat:
	$ cd /usr/ports/lang/gcc42 ; make
