Treat all targets serially at the toplevel. This allows

to specify
  nice gmake --jobs all check
and go to lunch, while a multiprocessor machine
will build everything using spare resources
and check the result thereafter.
Since concurrency of make is not restricted
in subdirectories, this should be a nearly
optimal way to do it.

Also teach the user about a configure switch.
