Subject: [PATCH] libgfortran: Use `__gthread_t` instead of `pthread_t`

It used to cause errors if a thread model other than `posix` was selected,
which looks like a leftover from a79878585a1c5e32bafbc6d1e73f91fd6e4293bf.

	* io/async.h (struct async_unit): Use `__gthread_t` instead
	of `pthread_t`.
