Modified Files:
        src/external/gpl3/gcc/dist/libsanitizer/sanitizer_common:
            sanitizer_mutex.h

Log Message:
Fix StaticSpinMutex::CheckLocked() on sparc32.

The lock gets set with atomic_exchange() -> __sync_lock_test_and_set()
which sets the value to 255 instead of 1.  Check for a taken lock
with "!= 0" instead of "== 1".  This should work on all architectures.
