Make tests run faster on typical platforms. 

Sadly not doable in make as it is notoriously bad at telling
you the parallelism being used by make -j.

If the HARNESS_JOBS environment variable has not been
set, this makes the perl script attempt to figure out how
many cpu's are available on anything windows/linux/macos/bsd like,
and if it can be successfully detected, we use that value.
if not, we use 1 as before.
