missing config/ax_tls.m4 link-time __thread tests

Description

Problem building userspace-rcu (in NetBSD 5.1 and older) because of missing TLS support at the libc level. Those NetBSD support __thread at the gcc level, but the support is not implemented in the libc. This fools config/ax_tls.m4 into thinking that it can use __thread.

A proper fix would be to link-test __thread support in the ax_tls.m4 script too.

Another, possibly simpler, way to achieve this would be to provide an
override, e.g. --with-pthread-tls, to force use the pthread TLS.

Thoughts ?
