[Development] Is qmake's bootstrapping parallel-safe?

I've been wondering if qmake's bootstrapping could be safely made with 
parallel building.

The reason for wanting to bootstrap qmake in parallel is that we have some 
archs that while they might not have a fast processor they have multiple ones 
available. If we can speed up the build there the better.

That being said, I have tried passing MAKEFLAGS="-j4" to the configure script 
but only a part of the bootstrap process went in parallel.

I later added the switch to the configure script itself and everything went 
OK. If it is safe but there are reasons not to support this in the configure 
script a distro-only patch would be enough.

Thanks in advance, Lisandro.
