The way the build knows which image was built is to build the kernel then look
in the output directory to see what extension was given to the artifact. iow,
it only discovers the dependency partway through the build; it doesn't know
the dependency when the build starts.

Either bitbake will have to put together the kernel's config at the start of
the build, then parse through it to try to determine which kernel will be
built, or we need some sort of mechanism that allows us to add dependencies
partway through a build, or we can add (yet another) build variable and hope
people are able to keep it in sync.

...or we could just add lzop-native as a static dependency in the off-chance that
it's needed.
