commit 82498129e0a91dfc3ed2c4ec3b2252f44655b83c
Author: Chris Patterson <pattersonc@ainfosec.com>
Date:   Fri Dec 18 08:27:57 2015 -0500

    configure: support systemd >= 209
    
    libsystemd-journal and libsystemd-daemon are now just
    part of libsystemd.
    
    Keep original systemd checks as a fallback.
    
    Updates charon-systemd/Makefile.am accordingly.
    
    Tested on:
    - debian wheezy (systemd v44)
    - ubuntu 15.10 (systemd v255).
