我通过 下载了 ubuntu 源代码git clone git://kernel.ubuntu.com/ubuntu/ubuntu-focal.git，
并根据https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel其中包含的 arm 构建过程，我执行以下操作：
LANG=C fakeroot debian/rules clean
LANG=C fakeroot debian/rules binary-headers binary-generic binary-perarch
我在命令之前或命令之后导出了ARCH=arm64 CROSS_COMPILE=aarch64-none-elf 或
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-，但最后却出现了错误。其中一条错误消息是You are building kernel with non-retpoline compiler, please update your compiler，我发现我可以通过更改配置来修复它（使用非 retpoline 编译器构建内核）所以我尝试了
LANG=C fakeroot debian/rules editconfigs
但是当我针对 arm64 架构执行此操作时，它会询问我。我尝试提供 ARCH 和 CROSS_COMPILE 选项，但它总是询问我是否要更改 amd64 配置。我该如何为这种构建方法Do you want to edit config: amd64/config.flavour.generic?提供 ARCH 和 CROSS_COMPILE 选项？fakeroot debian/rules
