Dear Maintainer,

The hardening flags are missing for autogroup and smbk5pwd
because the build system ignores them.

The attached patch fixes the issue. If possible it should be sent
to upstream (it might not apply cleanly to upstream because the
Makefile is modified by another Debian patch).

To check if all flags were correctly enabled you can use
`hardening-check` from the hardening-includes package and check
the build log (hardening-check doesn't catch everything):

    $ hardening-check /usr/lib/ldap/autogroup.so.0.0.0 /usr/lib/ldap/smbk5pwd.so.0.0.0
    /usr/lib/ldap/autogroup.so.0.0.0:
     Position Independent Executable: no, regular shared library (ignored)
     Stack protected: yes
     Fortify Source functions: yes
     Read-only relocations: yes
     Immediate binding: yes
    /usr/lib/ldap/smbk5pwd.so.0.0.0:
     Position Independent Executable: no, regular shared library (ignored)
     Stack protected: yes
     Fortify Source functions: yes (some protected functions found)
     Read-only relocations: yes
     Immediate binding: yes

(Position Independent Executable and Immediate binding is not
enabled by default.)

Use find -type f \( -executable -o -name \*.so\* \) -exec
hardening-check {} + on the build result to check all files.

Regards,
Simon
