powerpc: Fix define_machine so machine_is() works from modules
machine_is() was always returning 0 when used in a module, because
we weren't exporting the machine definitions. This was why sound
wasn't working on powermacs when CONFIG_SND_POWERMAC=m. Original
fix from Ben Herrenschmidt, further fixed by me.
