Modified files:
lib/libc_r/uthread uthread_mutex.c
Log:
Fixed a race condition during the first lock/trylock of a statically
initialized mutex. Statically initialized mutexes are actually
initialized at first use (pthread_mutex_lock/pthread_mutex_trylock).
To prevent concurrent initialization by multiple threads, all
static initializations are now serialized by a spinlock.
