In Poky its actually left "floating". If the build system has X headers
and SDL, qemu-native has graphics support, if not it becomes turned off
and won't have it. This has worked well as a compromise for us.

For contrast, qemu-sdk does build libsdl-sdk which does pull in an X
stack in Poky since its SDK must have graphical qemu.
