Heads up on Mesa git v. Wayland

[Marty Jack]

Yesterday there were some checkins to the Wayland support in Mesa that duplicate symbols of the general form wl_drm_* defined in /usr/include/wayland-client-protocol.h and wayland-server-protocol.h.  This causes the Mesa build to fail.

There is not yet a compensating checkin to Wayland that resolves this.  Hopefully Kristian will get to this soon and if there is hand work involved to break a circular dependency, he will post a recipe for the less experienced builders.
