On linux-next, we no longer able to select DEBUG_INFO directly due to this
patch:

https://lore.kernel.org/all/20220125075126.891825-1-keescook@chromium.org/

Thus, this patch will work on both the mainline and linux-next.

It works fine here.

$ git reset --hard v5.17-rc7
$ rm .config
$ make ARCH=arm64 defconfig debug.config
$ grep -i debug_info .config
CONFIG_DEBUG_INFO=y
