BUG#24507: Race conditions inside current NPTL pthread_exit() implementation.
If macro NPTL_PTHREAD_EXIT_HACK is defined then a hack described in the bug
report will be implemented inside my_thread_global_init() in my_thr_init.c.
This amounts to spawning a dummy thread which does nothing but executes
pthread_exit(0).
This bug is fixed in version 2.5 of glibc library.
TODO: Remove this code when fixed versions of glibc6 are in common use.
