Dear maintainer,
In effort to simplify creation and maintenance of derivate packages with
custom set of optional features disabled, here are patches that
enabling/disabling of optional feature is matter of changing exactly one
line in debian/rules.
Applied together, these patches do not alter default configuration (e.g
what is generated by dpkg-buildpackage) is any way, they just make
futher modifications simplier.

+Subject: Adjust build system to make systemd integration configurable
+
+Previously, systemd integration was built-in depending on whether
+libsystemd-dev was installed or not, without any option to configure it
+on per-package basis.
+
+With this change, systemd integration must be enabled explicitly
+with `WANT_SD_NOTIFY` variable.
