I don't know if it works as documented, I never checked it, but according
to GNU make manual, it should coordinate between sub-makes to run the
number of tasks in parallel as requested in top-level make invocation.
Passing down -j verbatim doesn't make sense because sub-makes are also
spawned in parallel so you would end up running more tasks than requested.
Manual also says it shall simply pass -j to sub makes when it's given
without a number to mean unlimited number of parallel tasks.
