Makefile: use -j8, allow manual PARALLEL_MAKE val
Set default -j to 8: even on a machine with less cores, using -j8 isn't really
going to slow down the build. On a machine with eight cores, -j8 is going to
speed up significantly.
By using '?=', allow passing a different -jN as PARALLEL_MAKE from the
enviroment.
