reopen 655891 thanks Dear Maintainer,
Sorry to bother you again, but there are still some hardening
flags missing. The CPPFLAGS ("Fortify Source") are not used. The
following patch fixes this:

(The patch from Moritz fixed the missing LDFLAGS: "Read-only
relocations", "Immediate binding").
To check if all flags were correctly enabled you can use
`hardening-check` from the hardening-includes package and check
the build log with `blhc` [1] (hardening-check doesn't catch
everything):
$ hardening-check /usr/sbin/ownership /usr/sbin/biosdecode
/usr/sbin/dmidecode /usr/sbin/vpddecode
/usr/sbin/ownership:
Position Independent Executable: yes
Stack protected: no, not found!
Fortify Source functions: yes (some protected functions found)
Read-only relocations: yes
Immediate binding: yes
/usr/sbin/biosdecode:
Position Independent Executable: yes
Stack protected: no, not found!
Fortify Source functions: yes (some protected functions found)
Read-only relocations: yes
Immediate binding: yes
/usr/sbin/dmidecode:
Position Independent Executable: yes
Stack protected: yes
Fortify Source functions: yes (some protected functions found)

Immediate binding: yes
/usr/sbin/vpddecode:
Position Independent Executable: yes
Stack protected: no, not found!
Fortify Source functions: yes (some protected functions found)
Read-only relocations: yes
Immediate binding: yes
Use find -type f \( -executable -o -name \*.so\* \) -exec
hardening-check {} + on the build result to check all files.
