File rsyslog-8.4.0-json-c-0.12-configure.patch of Package rsyslog

From: Andreas Stieger <andreas.stieger@gmx.de>
Subject: [PATCH] fix build with json-c 0.12 if it provides a compatibility json.pc
Date: Mon, 22 Sep 2014 20:40:53 +0100
Upstream: submitting
References: 

json-c on openSUSE provides a compatibility pkg-config for "json".
The autoconf check find it first, assuming it does not provide 
the function json_tokener_error_desc. Check for availability of 
function using AC_CHECK_FUNCS instead.
