- Tweak order of arch fs options to stick all floppy options together and

all MFS root options together and in the same order on all archs.
- Drop support for using the no longer existing 2.88 floppy image for CD
  booting on i386 via the EMUL_BOOT variable.
- Use a stock loader on the boot floppy rather than one without forth.
- Force the gzip of the mfsroot in release.9 to succeed.  This is useful
  when doing lots of rereleases when testing floppy changes.
- If an acpi kernel module exists, stick it on the boot floppy and for
  now always load it after the kernel.
