openwrt外部工具链（芯片厂商的，非openwrt自带）make编译报错 求助

[m0_37781301]

大大神好，我现在重新搭建openwrt环境，在make之前我将芯片厂商的mips交叉编译工具链解压到staging_dir下，在make menuconfig里设置了外部工具链，具体操作如下：
修改
Adcanced configurationoptions->

Use external toolchain
修改Base system->
Libc…configuration->交叉工具链所在路径
Libgcc…configuration->交叉工具链所在路径
Libpthread…configuration->交叉工具链所在路径
然后make报错：

求助大神！

报错信息就是找不到编译器，看看makefile 里面编译器的宏 ，设置一下

[m0_37781301]

请问我这个想法可行吗？依据之前说的先链接使用芯片厂商的工具链，在make
