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