That means a kernel built without CONFIG_PPC_47x will claim to support a 47x CPU and start booting, only to break somewhere later because it doesn't have 47x support compiled in. So guard the 47x cputable entries with CONFIG_PPC_47x. Note that this is inside the #ifdef CONFIG_44x section, because 47x depends on 44x.
