glamor uses libEGL/GBM and libGL, so this could only work with Mesa's
libGL (or the GLVND one in the future). Can amdgpu_dri.so work with
Mesa's libGL right now?

Also, I'm afraid there might still be cases where amdgpu-pro supports
new hardware before radeonsi, in which case amdgpu_dri.so needs to
support GBM for glamor and EGL in general.

Also note that Nvidia developers were talking about possibly creating an
nvidia specific GBM backend recently on the wayland-devel mailing list.
