Sorry I didn't get around to testing this before it was committed.

This breaks my build (See [1]), as the DRI2 loader is now built 
unconditionally, which fails without drm.h

I'm not sure exactly what problem this change is fixing, so I'm not sure 
how to address that.

Is it ok to restore the part which makes building the DRI2 loader 
conditional?
