We really need modules to use their own pthread_atfork so that __dso_handle properly identifies them. * sysdeps/htl/pt-atfork.c (__pthread_atfork): Hide function. (pthread_atfork): Hide alias. * sysdeps/htl/old_pt-atfork.c (pthread_atfork): Rename macro to __pthread_atfork to fix building the compatibility alias.
