Wayland/Weston with XWayland works on DragonFly

[karu.pruun]

I had a look but it seems the missing dependency is wayland-egl, which
I don't know how to build. It should be built by graphics/libEGL, but
a naively adding 'wayland' in the list of 'CONFIGURE_ARGS' in
graphics/libGL/Makefile.common does not work.

It'd be nice to have all the various toolkits (EFL, gtk30, Qt) build
on DragonFly. I'll dig further if I have time next week.
