Via makefiles yes, and only on directory level. But this requires to specify
the dependancies real precise. Currently afaik the packages/ dir uses
parallelization.

To take this a step further, it would take a multithreaded compiler I guess,
and a way to offer a lot of source at once to the compiler, with a hint to
use paralellism. But that is far, far off.
