Title: Add a second argument to bulk's -J to allow for a different number of jobs while preparing the build.

In most cases, the prepare jobs are IO bound and could use a different
setting.

In my case, where I only have 4 cores and the ports tree is nfs mounted, using 8 or 10 jobs for the prepare stages adds a between 50% and 70% speedup.
