[syslinux] PATCH: Build floppy image which contains HDT

[Kim Mik]

This patch builds a floppy image with contains HDT, so users of GRUB or GRUB4DOS can use HDT too, without installing Syslinux.


When you compile Syslinux, this floppy image isn't build automatically.
To build it, runthe following from the extracted Syslinux source:
  $ cd ./com32/hdt
  $ make hdt.img

As suggested by Pierre-Alexandre Meyer, all extra files required for building
the floppy image are in ./com32/hdt/floppy/:
  - hdt.cfg  ==> avaible as syslinux.cfg inside the floppy image
  - mtools.conf ==> Specifies hdt.img as floppy drive for the mtools programs
  - pci.ids (not included, can be downloaded from http://pciids.sourceforge.net)

hdt.c32 doesn't necessarily need the files modules.alias, modules.pcimap and
pci.ids, but in this patch those files are required for building hdt.img.
I did this because else hdt.img didn't build again when you update one of those
3 files, unless you run:

  $ cd ./com32/hdt
  $ make spotless
  $ make hdt.img

I don't know which way is preferred.
