    configure: cleanup classic dri drivers handling
    
    * Make sure that only drivers that are handled by configure.ac
    are included in DRI_DIRS.
    * Change with_dri_drivers default value to auto, and set enable
    autodetection, when enable_opengl is on.
    
    v2: Move "test" to the correct location.
    v3: Squash DRI_DIRS handling before the switch statement.

configure: use default dri drivers whenever opengl and dri are enabled

Easily reproduced and fixed with the above patch.

Vinson can we have a list of the configurations that you're building ? It would be rather useful.

I encountered the same issue and can confirm that 0001-configure-use-default-dri-drivers-whenever-opengl-an.patch fixes it for me.  Thanks!

    configure: use default dri drivers whenever opengl and dri are enabled

    Commit ee55500c22a(configure: cleanup classic dri drivers handling)
    cleaned up the logic handling autodetection of dri drivers, but missed
    the case when one can explicitly disable dri, and still request opengl.

    Fixes build issues for the following
    ./autogen.sh --disable-dri --with-gallium-drivers=swrast

    While we're here, explicitly clear with_dri_drivers whenever building
    without such drivers to prevent choking later on.

    v2: Simplify with_dri_drivers handling.
