The current set of qcow2 auto tests takes already quite a while, so I
don't think that this will change soon.
And if the "normal" users want to run more tests, they can simply use
"make check SPEED=slow" or SPEED=thorough, so IMHO no need to extend the
quick default list right now.

Hmm, sure, non-upstream patches are always a bad thing. But I still
don't see why you really need an extra Makefile target for this. In the
worst case, you could also simply change your script to run something
this instead:

 make $(grep ^check: tests/Makefile.include | sed s/check-block//)
