The 'terminal' branch does have its definition, but the 'terminal' branch looks out-of-date. (No commits since December.)

This is now provided by the EGL Wayland backend.  You will need a sufficiently recent Mesa git built --with-egl-platforms=wayland,drm

I find that Mesa has trouble updating the .so files during make install when they already exist.  You may want to check that you are actually using the ones you built.
