Recently, some security vulnerabilities in cracklib have been disclosed
[0].

For CVE-2016-6318, the disclosure message pointed out that if
cracklib is compiled without the FORTIFY_SOURCE compiler flag, the bug
can result in code execution and privilege escalation.

Unfortunately, that applies to us. Our exposure to the bug was mitigated
by the fact that cracklib is not used by our base system (it is used in
our GNOME system, however).

For this reason, I want to revert this commit until we have begun
"hardening" our packages [1].

Any objections?
