Currently, the following situation fails:
- Build an SDK and image. Make the image support graphics but not X11.
- Extract SDK and copy image somewhere outside of the Yocto workspace. Do
runqemu on the image.
This results in the error:
"Could not initialize SDL(No available video device) - exiting"
This seems to have fixed an issue I was seeing on FedoraCore 25 with
Morty with the same error. Did I miss comments regarding these changes?

This error occurs because libSDL attempts to load libX11 for video devices. When
it fails, qemu also fails.
Note that the same runqemu command will work fine from within the Yocto
workspace environment because it will use the native libSDL -- which supports
X11 -- rather than the nativesdk libSDL. In addition, the command will work fine
as long as DISTRO_FEATURES includes x11, because then the nativesdk libSDL will
be compiled with X11 support.
Although the example above may seem a bit silly, this is actually a pretty bad
error because it breaks the ability to build an SDK and image on one machine and
run it on a different machine.
Fix the issue by building nativesdk-libsdl with X11 support -- even when
DISTRO_FEATURES does not include X11 -- as we already do for libsdl-native.
