Find someone to add Hybrid-HFS support to "makefs -t cd9660", to make all mac68k and macppc images bootable and save manual steps on official releases

If that fails: change the auto build scripts to deal with mkisofs by special casing mac* and add an extra step to invoke the mkisofs machinery in src/distrib/cdrom

Add timing information to the autobuild html output, so each build shows the total wall time it took next to the successfull/fail counts in the overview page
