I should note that Chris didn't notice that I had already just pushed
this upstream.  And this neatly dovetails into a conversation I was
having with Chris anyhow (about another change we have that doesn't make
sense anymore).  There's two cases for how the kernel image is used:
- On the target, ${feed install} kernel-image, write to flash, whatever.
- On the host, user loads image to target, writes to flash in
bootloader.

In the second case, why do I want to waste space with an image on the
rootfs that I don't need?  Today, that image goes from deploy dir to
<however we give stuff to the end user> or right to the device.  I could
see, however, adding images to a defined place in meta-toolchain so that
this isn't an issue anymore and we could stop putting raw kernel stuff
into the deploy directory.
