commit 70fcd3516ded0755d5926e3c2939580c16ddf48b
Author: gregor herrmann <gregoa at debian.org>
Date:   Sun Nov 12 19:27:08 2017 +0100

    Fix autopkgtest: update debian/patches/hardening-flags.diff.
    
    Only add $ENV{*FLAGS} if the variables are set which is usually not the case
    at runtime and then leads to warnings about uninitialized values.
