[PATCH] libgcc: properly destroy mutexes on VxWorks

[Rasmus Villemoes]

Just as one needs run-time initialization of mutexes, one needs to
destroy them properly to allow the OS to release resources associated
with the semaphore.

==changelog==

libgcc/

	* config/gthr-vxworks.h (__gthread_mutex_destroy): Call semDelete.
