SDK编译linux内核修改配置报错如何为去解决呢

station p2用户，已经严格按照wiki搭建了编译环境，重装了干净的ubuntu 18.04系统和python 2，安装好了所有依赖，并且在不改动配置的情况下通过了所有编译。
现在的问题是需要在内核中增加一些模块，我的做法是进入kernel目录，并执行如下命令：
1：make ARCH=arm64 firefly_linux_defconfig
2：make menuconfig
3：在menuconfig中增加模块
4：make savedefconfig && mv defconfig arch/arm64/configs/firefly_linux_defconfig
5：cd ../ && ./build.sh kernel
编译即报错。
目前已经发现对menuconfig作任何修改，甚至不作修改，直接保存后写回defconfig都会报错，只能用原始defconfig还原才能通过编译。每次编译前都有make clean清理。

报错如下：
