openwrt默认会有autoconf、automake，但是没有autoconf-archive。
在编译外置包时可能需要使用autoconf-archive，以下是添加autoconf-archive步骤。

修改tools/Makefile

修改tools/Makfile添加autoconf-archive编译路径

添加autoconf-archive软件包

进入tools目录创建autoconf-archive文件夹，进入autoconf-archive创建Makefile

cd toolsmkdir autoconf-archivecd autoconf-archivetouch Makefile

Makefile内容如下

编译

make tools/autoconf-archive/{clean,compile} V=s
