This looks awesome. If I understand your patch correctly,
parallelization is active by default when one does "make -j6 check"
as you split the "check" target into multiple sub targets.
If one does a regular "make check" without the -j, then the sub
targets will simply be run in sequence.

Thanks for doing this. At this rate, I don't think you'll be able
to remain sober at the next GCC Summit :). (Editor's note: Daniel
and now myself promised Tom a drink for various very useful patches
that he wrote).
