Tinderboxes must be adjusted: new configure option --with-parallelism=<foo>

[David Ostrovsky]

Hi,

was wondering why some of my builds wasn't ready after 6 hours (after 
recent pull).

It turns out that with this commit: ed0b160041c46d74c81ba849f1f841eb5bdaba1c
the old configure options are gone: --with-num-cpus and --with-max-jobs.
The new one is --with-parallelism. Please adjust your tinderboxes 
correspondingly.

Regards
David
