g++.dg/tls/thread_local-order2.C fails when the toolchain is built for

__cxa_thread_atexit_impl.
This patch adds runtime testing for __cxa_thread_atexit_impl on
platforms that support weak symbols.
Regstrapped on x86_64-linux-gnu, also tested with gcc-13 on i686- and
x86_64-, and with ac_cv_func___cxa_thread_atexit_impl=no, that, on a
distro that lacks __cxa_thread_atexit in libc, forces the newly-added
code to be exercised, and that enabled thread_local-order2.C to pass
where the runtime libc has __cxa_thread_atexit_impl. Ok to install?
Seems fine to me. Any objections, Jason?
Jason, ping?

OK by me.
