(most of) customization options are documented there:

    http://rock-robotics.org/autoproj/advanced/customization.html

In your case, you want to do

    Autobuild.parallel_build_level = 4

in autoproj/init.rb

Could you send me the content of /proc/cpuinfo (I parse that to 
autodetect the parallel build level)

Note: I prefer that general questions go on rock-dev, that makes it 
easier for other people to find recurrent answers ;-)
