[PATCH] Create a dummy zImage if no valid platform has been selected.

Bad name, you are not creating a stripped zImage, but
a stripped vmlinux.

Why do anything at all when no platform is selected?

No quotes needed, standard style is

ifeq (,$(image-y))

> +image-y := zImage.strip
> +endif
> +
>  $(obj)/zImage:		$(addprefix $(obj)/, $(image-y))
>  	@rm -f $@; ln $< $@

Perhaps the minimal change (this is a degenerated case
anyway) would be to make this command non-failing?  Or
maybe that's not desired for "normal" builds?  Hard to
see how it ever could go wrong then, but that's wishful
thinking.  Maybe  ln -sf  would be best, it would just
create a dangling softlink in the allno case (and remove
the need for the rm command, too).

What do y'all think?
