In order to support the WL_bind_wayland_display extension it's necessary to
make use of render nodes, as DRI3 doesn't provide a mechanism for authenticating
client opened device node fds. However, this doesn't apply when Wayland support
is disabled, since the extension is no longer exposed.
Changes since v1:
- Make HAVE_WAYLAND_PLATFORM less inclusive (Martin Peres)
- Enhance DRI3 disabled warning (Martin Peres)
- Update commit message
