Add 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. Signed-off-by: H.

Disable unit-at-a-time mode on pre-gcc-4.0 compilers, it makes gcc use
a lot more stack due to the lack of sharing of stacklots:
