Be the way, could anyone clarify how this works? My idea was that
passing -j to port Makefile does nothing, as make/gmake on vendor's
Makefile is ran without any -j flags -> you get usual singlethreaded
build. However, I have a broken port, which uses gmake and something
like that:

sometarget:
  (cd xxx; make)

and that fails with -j (make: illegal option -- -). So is there
some magic with recursive make calls and -j?
