This is not the best approach as you disable PARALLEL_MAKE for both 
non-gplv3 and gplv3 versions.  Further, we want to get rid of 
PARALLLEL_MAKE setting as much as possible, so this patch is not helping 
that.

Did you try running on a large many core machine?  It might help if you 
have some other builds going also to stress the machine.

Sau!
