From: Jan Kiszka <jan.kiszka@siemens.com>

Replace self-invented / open-coded parallel build rules over the OE
pattern PARALLEL_MAKE. Should specifically reduce the spread of
PARALLEL_BUILD definitions in downstream layers. Mea culpa.

Maybe derive it from the other one "-j ${BB_NUMBER_THREADS}" ?

For make it is often suggested to use slightly more threads than
available CPUs, when some threads are doing IO you still get to use all
CPUs. There was a "*2" ...

I'm just using the OE pattern here.

I know, but same reasoning as above.

And given that cpu_count is cores*threads with, typically, threads >= 2,
this overcommittment is less important today.
