fix:

	* sysdeps/x86/nptl/bits/pthreadtypes.h (pthread_mutex_t):

Seems OK (as far as I can tell, nothing references the name of this

filed, referenced in the ChangeLog entry and NEWS and closed if the issue 
was present in a release.

Tested x86_64 and x86 to verify that both have no FAILs, filed and
closed 17084 with a mention in the NEWS.
