This option masks all unused command line argument warnings, which can hide potential issues, such as an architecture Makefile adding an unsupported flag to KBUILD_AFLAGS or KBUILD_CFLAGS, which will cause all as-option and cc-options to silently fail due to -Werror with no indication as to why in the main kernel build. Remove this flag so that warnings of this nature can be caught early and obviously in a build.
