I think we should make the TLS option a blind option, and have it
unconditionally enabled, except if the architecture doesn't support it.

#ifndef DOC_HIDDEN
#ifdef HAVE___THREAD
#define TLS_PFX         __thread
#define TLS_PFX         /* NOP */

static TLS_PFX snd_local_error_handler_t local_error = NULL;

So when thread support is available, alsa-lib assumes TLS support is there.
