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.

Yes, you'll need to pull up the source; the diff doesn't provide enough context. tune-mcpu is used in the body of the else branch hinted at by the diff.
