#8836: pthread_join on a detached pthread crashes

pthread_join should return EINVAL if the thread cannot be joined. -
http://pubs.opengroup.org/onlinepubs/7908799/xsh/pthread_join.html
A thread in a detached state cannot be joined -
http://pubs.opengroup.org/onlinepubs/7908799/xsh/pthread_attr_setdetachstate.html
It would appear that the correct behavior would be to modify the
pthread_join implementation to return EINVAL if the caller attempts to
join a detached thread.
Attached is an excerpt from a POSIX compatibility test that covers this
specific functionality. (2-1.c). This test crashes on rev 44457, producing
the error in backtrack.txt.
Attached is also a patch to amend pthread_join's behavior.
