Lets take a step back and think about this for a minute.

If you build qemu-native configured with sdl, its likely you do want X
support. As this stood, the linkage with libxext was problematic.
Robert's patch makes the situation deterministic so in that sense its as
correct as the various other determinism patches.

The issue is that in some builds, you relied on x11-native not being
built and this is now showing up as an issue. What can be done is to
make the libxext dependency conditional on x11 in DISTRO_FEATURES as
we've done in other cases. It doesn't really make this invalid or a
regression, just that like other determinism fixes, we've resolved this
in a way means we need to rethink a few things.

I'd strongly suggest people think about whether they do really want x11
in "native" DISTRO_FEATURES since in reality, I suspect most people do.

So I'll take a patch making the dependency conditional but I don't
believe its what most people actually want.

Cheers,

Richard
