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.
