[syslinux] Syslinux multifs support

[Tal Lubko]

Hi Poma

I've tested it again with 2 machines. Each machine has only 1 disk (multifs
isn't needed for that but that is my start point).
- some I7 machine - seems to be working
- some Atom machine - doesn't seem to be working

I'll check my BIOS mode and let you know about it.
I'm also going to check it with more than 1 disk.
