UPSTREAM: abuild: Treat command line for recursive invocations as bash array

Browse source 
This fix changes the $cmdline variable that is used for recursive
parallel abuild invocations through xargs from a string to a true bash
array (like $@). This allows bash to properly preserve and pass on
whitespace in parameters, like you get from invocations such as:

 util/abuild/abuild -c 32 -t "MY_FIRST_BOARD MY_SECOND_BOARD"

Also add a mechanism to better spread CPUs across targets, since
otherwise we can leave a lot of CPUs idle if we're trying to build only
a few boards in parallel.
