Subject: [PATCH] Make autogen.sh a bit more robust and informative   * Default
 to sysconfdir as configured at build time   * Return an error message and
 value if the specified config file is not found   * Support legacy option of
 using $1 as the config file value, without breaking "autogen.sh -u"
