Those come from a statically-linked libldap_r:
$ nm -A -u /home/nm/sw/nopath/openldap-64/lib/libldap_r.a|grep exit
/home/nm/sw/nopath/openldap-64/lib/libldap_r.a[tpool.o]: .ldap_pvt_thread_exit U -
/home/nm/sw/nopath/openldap-64/lib/libldap_r.a[thr_posix.o]: .pthread_exit U -
/home/nm/sw/nopath/openldap-64/lib/libldap_r.a[init.o]: .atexit U -
