How'd sparc64 get set? One of the open issues after merging sparc and sparc64. I have never got around to find a proper solution so we adjust the config based on the ARCH= setting. So allmodconfig + allyesconfig will always be sparc64. And allnoconfig will always be sparc. Davem has rightfully complained about this before.
