From: Johannes Berg <johannes.berg@xxxxxxxxx> To speed up the build a little bit, avoid evaluating cc-ifversion for every objtool invocation. The variable needs to be evaluated every time it's used because of the $(if $(part-of-module)...) in it, but we don't need to call out to the compiler to get its version every time.
