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.

+# This script generates the dummy HFS filesystem used for the PowerPC boot
+# blocks. It uses hfsutils (emulators/hfsutils) to generate a template
+# filesystem with the relevant interesting files. These are then found by
+# grep, and the offsets written to a Makefile snippet.
+#
+# Because of licensing concerns, and because it is overkill, we do not
+# distribute hfsutils as a build tool. If you need to regenerate the HFS
+# template (e.g. because the boot block or the CHRP script have grown),
+# you must install it from ports.
