[PATCH] rename kernel.elf to kernel.img (Re: [PATCH] i386-qemu port)

[Robert Millan <rmh@aybabtu.com>]

If you check my earlier patch, you'll see i386-qemu.rmk is just a stub
that includes i386-coreboot.rmk.  This is to reduce code duplication
(untill we have a more flexible build system).

This patch renames kernel.elf to kernel.img in ELF platforms, so that
more variables / etc can be shared with non-ELF ones.

It has no user-visible effect.

  The DRM opt-in fallacy: "Your data belongs to us. We will decide when (and
  how) you may access your data; but nobody's threatening your freedom: we
  still allow you to remove your data and not access it at all."
