Aren't reproducible builds more important than automagically enabled
graphics support, what if such automagically enabled qemu-native gets
reused from sstate on headless server without graphics support?

We can extend documentation to say that in order to enable graphics
support for qemu-native you need to set
PACKAGECONFIG_pn-qemu-native += "foo bar"
in local.conf (or to remove some to disable it, but enabling explicitly
is imho better because we don't have graphics native support in
ASSUME_PROVIDED).
