From dc3f2250908587710f109c80ddf8a94f0bc40b82 Mon Sep 17 00:00:00 2001
From: Jonathan Richardson <jonathan.richardson@broadcom.com>
Date: Fri, 6 Apr 2018 10:49:04 -0700
Subject: [PATCH] autotools: Add option to disable installation of systemd conf
files
Add option to configure.ac to enable or disable install of systemd conf
files. If --with-systemdsystemunitdir is passed to configure then the
files will be installed to the provided directory. If the option isn't
provided then the value is determined from the systemd pkgconfig file,
if found in PKG_CONFIG_PATH.
This change is required because Makefile.am always installed the files
to a hard coded path that couldn't be changed.
