New description:

 By The Open Group Base Specifications Issue 6, pthread_mutex_trylock()
 should return EBUSY if the lock is already held (
 http://pubs.opengroup.org/onlinepubs/009695399/functions/pthread_mutex_lock.html
 ).

 On RTEMS 4.11, it instead returns EDEADLK

Comment (by joel.sherrill):

 Nick.. can you check mutextranslatereturncode.c and see if it is OK now? I
 don't seem to be able to match the EDEADLK to the core status I think
 would match.
