-    imv-swid: Use pkg-config to check for libjson-c
-    
-    The package/library is called libjson-c on recent distributions.
-    Some like Ubuntu 14.04 provide symlinks with the old name but these
-    will eventually disappear.  Using pkg-config allows us to easily check
-    for it (with a fallback) and configure the proper compiler flags.
-    
-    Fixes #663.
