#     kbuild: Stop using '-Qunused-arguments' with clang
#     
#     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.
