The libdri.so, which is expected by X at /usr/lib/xorg/modules/extensions/libdri.so,
is not built. It is normally built by the DRI part of xerver-xorg-video-imx-viv.
Only the EXA part is done.
Hacking to make it built makes some compilation errors, with xserver version 1.14
(though it worked fine with xserver 1.12)
Is there a patch somewhere, or does that mean that libdri.so should not be needed ?
