Per our discussion on the trail to the Lower Elk lake overlook, I think you should leave out the #ifndef NO_PIC/#endif around the call to dlctl() in __cxa_thread_atexit_impl(): NO_PIC is never defined in libc and we don't really have an interest in optimizing for a future arch that doesn't support shared libs.
