Bug-Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=779768

In systemd v209, released over a year ago, the various libsystemd-* libraries
(libsystemd-journal.so, libsystemd-login.so, libsystem-daemon.so,
libsystemd-id128.so) were merged into a single libsystemd.so library to reduce
code duplication and avoid cyclic dependencies [1].

The patch can be as simple as

diff --git a/configure.ac b/configure.ac
index 1f051ec..2599aa2 100644

If you want to support systemd versions <= 208, you'll need to add a fallback check.

For this you'll need to do the pkg-config check for libsystemd separately, like:

PKG_CHECK_MODULES([SYSTEMD], [libsystemd],,
                  [PKG_CHECK_MODULES([SYSTEMD], [libsystemd-journal])])
