There's a few tests whose do_test() is supposed to time out or terminate with a signal. Tests communicate it to the test skeleton by defining EXPECTED_SIGNAL or EXPECTED_STATUS and the skeleton completes with success code when that happens. Running test suite in direct mode by default changes that, as a result test running script reports failures for the tests that actually pass or hangs. Instead of switching to direct test running when building for noMMU use vfork() and exec() the test in the child process in direct mode. This makes the default test process behavior the same on MMU and noMMU targets.
