I left out the runtime dependency stuff because the xen-qemu package
will end up with a dependency on libsdl if it's enabled. I was under the
impression that this is sufficient though I'm not exactly sure how the
dependency is created. Honestly I was happy to write it off as
bitbake/OE magic. I've tested dom0 images with sdl enabled and disabled
and the xen-qemu package will pull the SDL library into the image if
it's enabled.

Are you seeing different behavior?

Regards,

P.S. There's a dependency issue with this patch anyways so I'll send out
a v2 with a minor fix tonight.
