ps on BSD hosts (like OS X) do not provide the --no-headers switch nor understand the AIX format descriptions. Make the call for ps portable and filter the relevant line from output (including the header) with sed. Also switch from pgrep to ps to get the list of children and use the same mechanism as for pgid.
This patch makes the MAKEALL script cleanly stoppable on bare OS X when using the parallel builds of targets.

Oumpf, just realized that the 'ps -g' is _not_ portable though. The linux variant selects by session OR group name while the BSD variant uses the process group. I'm looking for a better solution which is portable.
