本文主要是介绍arm64平台make menuconfig引起问题丢失CONFIG_XXX，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
现象:
SYNC include/config/auto.conf.cmd
*
* Restart config...

*
* General setup

Compile also drivers which will not load (COMPILE_TEST) [N/y/?] n
Local version - append to kernel release (LOCALVERSION) []
Automatically append version information to the version string (LOCALVERSION_AUTO) [Y/n/?] y
Build ID Salt (BUILD_SALT) []

解决: 原因有一些必要的配置丢失,内核跑飞.
source /etc/profile,安装交叉编译器的脚本配置的环境变量就可以生效
