I recompiled mesa/mesa using
========================

util/modular/build.sh $PREFIX  -o mesa/mesa --confflags "--enable-debug --enable-kdrive  --with-dri-drivers=i915 --with-gallium-drivers=i915,swrast --localstatedir=/var"

and ran glxinfo:
===========

name of display: :0
couldn't open libtxc_dxtn.so, software DXTn compression/decompression unavailable
i915_drm_buffer.c:86:i915_drm_buffer_create_tiled: Assertion `0' failed.

Never heard about  libtxc_dxtn but found it at freedesktop.org.
After cloning, building and installing libtxc_dxtn:
