hopefully fix powermac bootable CD problem, check whether mkhybrid or

mkisofs is used, if mkhybrid do as we always have, if mkisofs add
args: -hfs-bless $n/install/powermac.  note this *REQUIRES* the
mkisofs from woody, potato's will not work.

don't make HFS images for CDs > 1, its not needed.

I will have someone test this to ensure it works asap.
