The new KERNBASE allows my RB800 to boot without having to modify it, so that's a definite improvement there.
Will check for regression on G4 / G5 / POWER9 (and maybe test the X5000, if I can finally get uboot loader set up on it so I don't have to futz with mkimg to build test kernels) tomorrow.

Fix 32-bit build.
