Does not boot anymore with self compiled Mesa with VC4 support

[jonnius]

This is an attempt to solve #16. Steps to reproduce:

1. Install Ubuntu Mate with all updates on Raspberry Pi 3B
2. Build and install new Libdrm (instructions from here)

sudo apt-get install \
    xutils-dev libpthread-stubs0-dev \
    automake autoconf libtool
git clone git://anongit.freedesktop.org/mesa/drm --depth 1
cd drm
./autogen.sh \
    --prefix=/usr \
    --libdir=/usr/lib/arm-linux-gnueabihf
make
sudo make install

3. Build and install Mesa with VC4 support (instructions from here, but slightly adapted to avoid missing dependencies and another issue). Beware: The make step takes a lot of hours on the Raspy. You might want to try make -j2, hoping that the RAM would be sufficient.

sudo apt-get install \
    flex bison python-mako \
    libxcb-dri3-dev libxcb-dri2-0-dev \
    libxcb-glx0-dev libx11-xcb-dev \
    libxcb-present-dev libxcb-sync-dev \
    libxshmfence-dev \
    libxdamage-dev libxext-dev libxfixes-dev \
    x11proto-dri2-dev x11proto-dri3-dev \
    x11proto-present-dev x11proto-gl-dev \
    libexpat1-dev libudev-dev gettext \
    autogen zlib1g-dev libxxf86vm-dev libxrandr-dev

git clone git://anongit.freedesktop.org/mesa/mesa --depth 1
cd mesa
./autogen.sh \
    --prefix=/usr \
    --libdir=/usr/lib/arm-linux-gnueabihf \
    --with-gallium-drivers=vc4 \
    --with-dri-drivers= \
    --with-egl-platforms=x11,drm \
    --enable-autotools
make
sudo make install

3. Install Unity8 by running install.sh

4. Reboot

Result is that the Raspy does not boot anymore. The monitor remains black and I cant access it via SSH.

I started over with a new SD card and did all the compiling on USB Stick. This time the result is Ubuntu Mate only booting in low graphics mode.
