string: Implement strerror in terms of strerror_l
If the thread is terminated then __libc_thread_freeres will free the storage via __glibc_tls_internal_free. It is only within the calling thread that this matters. It makes strerror MT-safe. Checked on x86-64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, and s390x-linux-gnu. Tested-by: Carlos O'Donell <carlos@redhat.com> Reviewed-by: Carlos O'Donell <carlos@redhat.com>
