Well, you seem to use a vendor make, not GNU make, ergo you should consult
the documentation of that one.

It works everywhere. For instance with GNU make I regularly do -j 10
makes (on the right machines of course ;-) ) and bootstraps. Meanwhile
also libjava is built in parallel.

Yes, there doesn't need to be a FAQ. With the right make it simply works
(modulo the occassional bugs). I would advice you to simply get GNU make,
and be done with it.
