[RFC PATCH] tests: print failed test numbers at the end of the test run

[Jens Lehmann <Jens.Lehmann@web.de>]

On modern multi-core processors "make test" is often run in multiple jobs.
If one of them fails the test run does stop, but the concurrently running
tests finish their run. Finding out what test is broken involves a lot of
scrolling. That gets even worse when the -i option is used.

If one or more tests failed, print a list of them before the test summary:

failed test(s): t1000 t6500

fixed   0
success 7638
failed  3
broken  49
total   7723

This makes it possible to just run the test suite with -i and collect all
failed test scripts at the end for further examination.

Maybe I'm missing something completely obvious, but I always have a hard
time finding out which test scripts did fail in a test run with -j30.
