Subject: posix: Change pthread_once to be SMP safe.

Change pthread_once from using disabled pre-emption to using a
pthread mutex making it SMP safe. GCC using a posix threading
model uses pthread_once.

The pthread mutex requires at least 1 mutex is configured so
confdefs.h has been updated to account for the internal
mutex.
