CONFIG_PPC_MULTIPLATFORM is just a meta config that enables you to
configure for multiple platforms.  In this way it is perfectly comparable
to CONFIG_IA64_GENERIC.  The only difference is that CONFIG_IA64_GENERIC
enables _all_ platforms with one option, whereas CONFIG_PPC_MULTIPLATFORM
still lets you chose which one of the platforms to support at all, but you
can chose to support more than one in a single kernel.
