 Steps:
 1. Call pthread_sigmask with a randomly generated
 value of  how that is checked to make sure it does not equal any of the three defined
 values of how which are SIG_SETMASK, SIG_BLOCK, or SIG_UNBLOCK. This should
 cause pthread_sigmask() to return EINVAL. If it doesn't, then fail, otherwise pass.
