[PATCH 4/7] arc: replace cc-option-yn uses with cc-option
cc-option-yn can be replaced with cc-option. ie. Checking for support: ifeq ($(call cc-option-yn,$(FLAG)),y) becomes: ifneq ($(call cc-option,$(FLAG)),) Checking for lack of support: ifeq ($(call cc-option-yn,$(FLAG)),n) becomes: ifeq ($(call cc-option,$(FLAG)),) This allows us to pursue removing cc-option-yn.
