"make isoimage" support; FDINITRD= support; minor cleanups
This patch adds a "make isoimage" to i386 and x86-64, which allows the
automatic creation of a bootable CD image. It also adds an option
FDINITRD= to include an initrd of the user's choice in generated floppy-
or CD boot images. Finally, some minor cleanups of the image generation
code.
