Hi Michal, Here's a ARC build system quirk that we are trying to change. I would appreciate if you could take a glance and suggest if that is silly or better way. Would we be inducing more shell invocations now for build ? Also I could not find an existing construct in /scripts/Kbuild.include so opencoded the pre-processor check.
