Unfortunately I saw that a bit late, but this is breaking our use case.

Weston works perfectly fine on non-GPU systems without EGL/OpenGL ES
using pixman renderer. Currently libgbm is still a compile time
dependency, but I have a merge request pending which should drop this
dependency, then the DRM backend can be compiled fine with only KMS
support.
