Dear Maintainer,

The CPPFLAGS hardening flags are missing because they are not set
in debian/rules.

The following patch fixes the issue.

    diff -Nru libmusicbrainz-2.1-2.1.5/debian/rules libmusicbrainz-2.1-2.1.5/debian/rules

              --prefix=/usr
            touch $@

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/libmusicbrainz.so.4.0.3
    /usr/lib/libmusicbrainz.so.4.0.3:
     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: 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
