make it possible to build without the obnoxious forced -j to make

Browse source 
Rework --with-parallelism to not add any extra -j to make if 0
or --without is used. This requires explicit -j usage, which
- builds even compilerplugins in parallel
- builds 'make -C sw/' in parallel (since you don't forget the -j)
- avoids jobserver disabling if -j is explicitly passed to the toplevel make

IMO this is just a relic of the old build system and the option should
be dumped altogether, but I don't feel like arguing right now.
