Comment 1 for bug 760387

The simplest way to fix this would be to just change 'make check' back out of using subunit output.

Pros:
 * the failure email will be more concise
 * the subunit stream seems reasonably often not to be able to be parsed by subunit so it's not reliably useful
 * other people running make check will not be surprised by reams of output
 * this will avoid some complexity about checking the output that's sometimes caused pqm to fail open

Cons:
 * perhaps people do like subunit? (I like the idea in general but I don't find it very useful with pqm).
 * changing it might break something in pqm
