The pthread_exit symbol was moved using scripts/move-symbol-to-libc.py. No new symbol version is needed because there was a forwarder. The new tests nptl/tst-pthread_exit-nothreads and nptl/tst-pthread_exit-nothreads-static exercise the scenario that pthread_exit is called without libpthread having been linked in. This is not possible for the generic code, so these tests do not live in sysdeps/pthread for now. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
