If you have 2 processors, "make -j 2" will speed up compiles by
telling make to spawn 2 compile jobs at a time, instead of just 1.
This will speed up compilation time, but won't change the way the
compiled program runs.
Using a "-j" value greater than the number of processors available
just tends to slow things down. (Causes unneeded context switches)
