Currently it prevents users to run in a wayland-only environment without manually forcing the backend. The SDL2 wayland backend has been supported by distributions for a very long time (e.g. in Fedora, first available 8 years ago), and is now considered stable and becoming the default for new SDL2 releases. Instead of requiring the x11 backend to exist by default, let new qemu releases run with the default chosen by the installed SDL2 version. Signed-off-by: Erico Nunes Reviewed-by: Daniel P.
