It was intel. Hmm.. you?

All I read was not to use Gallium, as there is a _specific_ DRI2 EGL
driver which Wayland wants to use. IE.. any Gallium is bad. I might be

I've passed --disable-gallium, and scribbed all the other gallium
related stuff. I'm not sure how this sits if you want / need to build a
gallium driver for your graphics card though..
Perhaps build the EGL drivers separately with --disable-gallium? That
said, I've no idea if that has any chance of working.
This was my configure line for building mesa:
(from config.log, so probably missing some "" qouting around args).
./configure --disable-gallium --disable-glu --disable-glut --disable-glw
--with-dri-driverdir=/usr/local/lib/dri --with-egl-displays=x11 drm
--enable-glx-tls --enable-gles-overlay --enable-gles1 --enable-gles2
You might want to try adding -with-egl-displays="x11 drm" to get rid of
the gallium bit
