From ec630dc256b3e9cb80cd3ca9872c5a405ae21646 Mon Sep 17 00:00:00 2001
From: Thomas Haller <thaller@redhat.com>
Date: Tue, 9 Jan 2018 07:30:31 +0100
Subject: [PATCH 6/6] libnm: cleanup include in "libnm-core/nm-json.c"
We already define _GNU_SOURCE in "config.h", depending
on configure checks.
Also, we always should first include "config.h" (which means
to first include "nm-default.h").
Also, we don't need the entire <link.h>, <dlfcn.h> suffices.
(cherry picked from commit 84576ce86155e195985a1924c90782eb9e2e5beb)
