We could stuff all of the initobjs into an initobj.a, and use that for
linking. ld will only pick up the object files that are actually needed
then. This means we probably compile a serial port thingy too many, but
they're rather small.

For chipset specific stuff (once we get there), it can be
initobj-$(CONFIG_SOUTHBRIDGE_X_Y) += ...
