Committed: io/async.h: Use __gthread_mutex_t, not pthread_mutex_t.

[Hans-Peter Nilsson]

These pthread_mutex_t were obviously meant to be
__gthread_mutex_t. See other declarations. Not being that,
broke cris-elf build at r264070, restored with this patch. Also
regtested on native x86_64-pc-linux-gnu.

I'm not sure know why no other bare-iron target saw this, but
perhaps it's because my newlib is a bit dated (...looks... yes,
looks like newlib has grown pthreads since then, but that
doesn't excuse this flaw). Still, there may be other similar
flaws behind #ifdefs, this is just a build-fixing patch.

Committed as obvious.

Thanks for the fix!
I mentioned the need to fix this in
https://gcc.gnu.org/ml/fortran/2018-09/msg00006.html
and i hope Thomas and Nicolas will take care of the rest of the
comments soonish.

cheers,
