Introduce multiple make jobs (parallelization) support. When enabled, -jX is

passed to the top level vendor Makefile in build stage, where X is number of
CPU cores by default.  The whole system is opt-in, ie. ports need to be enabled
individually.  There is a global override available for adventurious users.
