Debian uses the -j 10 option of SIP v4. This dates back to 2007 so I don't
know why not -j 1.

However I'm not sure how this is related to the original thread. If you are
suggesting to disable parallelism completely, then isn't it still useful for
building different Qt modules (QtCore, QtGui, etc) in parallel?
