If one of the qtests fails, the TAP driver prints out a message like:

  ERROR - too few tests run (expected 3, got 1)

which fails to tell you which test program failed. This is a critical
ommission when many tests are running in parallel as their output is
interleaved. The improved message is:

  ERROR endianness-test - too few tests run (expected 3, got 1)
