Don't enable atomics in NO_THREADS configurations.

In configurations without threads, we're not thread-safe anyway. Instead
use the refcount_lock.c implementation which, in turn, calls into
thread_none.c, so this turns into a plain refcount.

This avoids a build issue on platforms which define NO_THREADS, use C11,
lack C11 atomics, and are missing a __STDC_NO_ATOMICS__ definition. The
platforms ought to define __STDC_NO_ATOMICS__ or implement them, but
atomics are also unnecessary overheard in NO_THREADS configurations
anyway.
