libc/stdlib: Add __cxa_thread_atexit_impl() hook.
The __cxa_thread_atexit_impl() helper is needed for mainly c++ runtime
libraries to support destructors for thread local storage using LIFO.
The _thread_finalize() is implemented based on OpenBSD variant with few
exceptions: less restrictive destructors calling scheme and c++ runtime
preserves implementation details how it orders (or even uses) this libc
addition. Based on other BSDs and libsdc++/libc++ code this is least
intrusive method to have pthread_exit() hooks in libc runtime. By the
looks, in base system nothing was using libstdc++ internal version.
While there, enable __cxa_thread_atexit_impl() usage in gcc80 libstdc++.
