perf_bfd_lock() and perf_bfd_unlock() are the callbacks given to
bfd_thread_init(), so by design they acquire and release the lock on
libbfd's behalf and the lock state differs between entry and exit.
clang's thread safety analysis, which perf builds with as an error,
flags both:
util/libbfd.c:56:1: error: mutex 'bfd_mutex' is still held at the end of function [-Werror,-Wthread-safety-analysis]
util/libbfd.c:60:2: error: releasing mutex 'bfd_mutex' that was not held [-Werror,-Wthread-safety-analysis]
Mark both functions NO_THREAD_SAFETY_ANALYSIS so that libbfd.c compiles
with "make CC=clang BUILD_NONDISTRO=1".
