Giacomo Tesio 2481b01515 qa: introduce runners and more tests for newlib
For each test, if a script exists with the same name of the test
plus the .runner suffix, the runner is run instead of the test.

As a first example qa/lib/newlib/testsuite/atexit is run by
qa/lib/newlib/testsuite/atexit.runner.

These .runner scripts allow more complex checks of the side effects
generated by the test.
