A specific Android version has corresponding Linux kernels. It is likely
developers can find what they want, as they should work on an relative
old kernel source tree.

Given Namhyung and you both are concerned for removing the doc, I have

as this patch is not really related to cross building fix.

Thanks,
Leo
