Change the way powerpc bootable CDs are generated to work around a bug
in hybrid image generation in cdrtools. This produces a small HFS partition
containing loader, mapped in by an oddly-formed APM table using a new
feature in makefs. This does not appear to work yet on early-model G3
systems, which will be fixed later, but produces bootable CDs on
everything else.
