Bug 20252 – posix.mak does not stop on failure

Running "make -j3 -f posix.mak unittest", a FAIL appeared, but make continued checking. Thus this FAIL was gone unseen: [...] ****** FAIL debug64 std.algorithm.sorting core.exception.AssertError@std/algorithm/sorting.d(1963): You seem to have improved sort!

Running make with -j3 will use multiple threads. If one thread fails, the others will continue to run. It's how make is designed to run. I suspect this is the cause of the behavior you're seeing. If not, please reopen and clarify.
