make menuconfig 出错

[miyouzi]

使用SDK OpenWrt-SDK-15.05.1-ramips-mt7621_gcc-4.8-linaro_uClibc-0.9.33.2.Linux-x86_64.tar.bz2 按照 教程 操作。 报错：

但是跳过这一步，直接 make ，可以直接编译出 ipk ，并可以使用，请问这是什么问题。 环境：Ubuntu 18 LTS 64bit

那个教程里的方法我只在lede 17.01上测试过，可能openwrt 15.05不太一样。

我平常用这个方法来build，可以绕过openwrt/lede的buildroot脚本，更简单通用：

@wangyu- 谢谢。才知道原项目makefile已自带交叉编译功能。先已成功编译出tinyfecVPN、tinyPortMapper，移植到路由可运行。
