Dear Maintainer,

The LDFLAGS hardening flags are missing because they are
overwritten in debian/rules.

DEB_*_MAINT_APPEND is the preferred way to set additional flags
(see man dpkg-buildflags for more information). For more
hardening information please have a look at [1], [2] and [3].

The following patch fixes the issue.

To check if all flags were correctly enabled you can use
`hardening-check` from the hardening-includes package and check
the build log (for example with blhc [4]) (hardening-check
doesn't catch everything):

    $ hardening-check /usr/bin/skanlite
    /usr/bin/skanlite:
     Position Independent Executable: no, normal executable!
     Stack protected: no, not found!
     Fortify Source functions: unknown, no protectable libc functions used
     Read-only relocations: yes
     Immediate binding: no not found!

(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
