Well, I took some time and tried to port it to python3. Eventually I 
managed to get it compiled with:

find -name '*.py' | xargs 2to3 -w &&
patch -p1 -i ../MesaLib-10.4.3-python3-1.patch &&
./autogen.sh PYTHON2="python3" \
              CFLAGS="-O2" CXXFLAGS="-O2" \
              --prefix=/usr \
              --sysconfdir=/etc \
              --disable-dri3 \
              --enable-sysfs \
              --enable-texture-float \
              --enable-gles1 \
              --enable-gles2 \
              --enable-osmesa \
              --enable-xa \
              --enable-gbm \
              --enable-glx-tls \
              --with-egl-platforms="drm,x11" \
              --with-gallium-drivers="r600"

I still need to test it at run-time and if that goes well I'll likely 
build LFS & BLFS by the official books next and see what else needs to 
be done to produce the complete patch and instructions.
