[PATCH] x86: Kconfig: make CMDLINE_OVERRIDE depend on CMDLINE

From: Anders Roxell
Date: Fri Jan 24 2020 - 06:46:38 EST


When trying to boot an allmodconfig kernel that is build with
KCONFIG_ALLCONFIG=$(pwd)/arch/x86/configs/x86_64_defconfig, it doesn't
boot since CONFIG_CMDLINE_OVERRIDE gets enabled. Which forces the user
to pass the full cmdline to CONFIG_CMDLINE="...".

Rework so that CONFIG_CMDLINE_OVERRIDE gets set only if CONFIG_CMDLINE
is set to something except an empty string.

Set this option to 'Y' to have the kernel ignore the boot loader
command line, and use ONLY the built-in command line.
