[PATCH] kbuild/mkspec: Fix architectures where KBUILD_IMAGE isn't a full path

[Tom Rini <trini@konsulko.com>]

On some architectures, such as arm64, KBUILD_IMAGE is not a full path
but instead just the build target.  The builddeb script handles this
case correctly today and will try arch/$ARCH/boot/$KBUILD_IMAGE so we
can just borrow that logic and adapt it slightly for spec file syntax.

It is currently a mixed-bag on if architectures will use a build target
(arm, arm64, arc are certainly by inspection and a few others 'may') or
a full path (x86, blackfin, s390).  Given that builddeb gets this case
correct, I think changing mkspec is the right way to go here.
