And you are wrong - latest Make does not break reasonably old kernel builds such as 
v2.6.30.

Latest binutils insta-breaks the build over 130,000 commits, including the latest 
released kernel.

Please change that .size build error to a build warning, to avoid this unnecessary 
collateral damage.

Thanks,
