The Linaro use the library libjpeg-turbo directly and not is necessary to install as I do in Raspbian + opencv + libjpeg-turbo
The installation of Ubuntu-Linaro is quite simple, and can be downloaded from the berryboot, in the same way as I did with Raspbian.
Well I find some troubles when I tried to install opencv in Linaro.
When I added the requisists to install openCV
sudo apt-get -y install build-essential cmake pkg-config libpng12-0 libpng12-dev libpng++-dev libpng3 libpnglite-dev zlib1g-dbg zlib1g zlib1g-dev pngtools libtiff4-dev libtiff4 libtiffxx0c2 libtiff-tools
sudo apt-get -y install libjpeg8 libjpeg8-dev libjpeg8-dbg libjpeg-progs ffmpeg libavcodec-dev libavcodec53 libavformat53 libavformat-dev libgstreamer0.10-0-dbg libgstreamer0.10-0 libgstreamer0.10-dev libxine1-ffmpeg libxine-dev libxine1-bin libunicap2 libunicap2-dev libdc1394-22-dev libdc1394-22 libdc1394-utils swig libv4l-0 libv4l-dev
I had to add this library, if not our programs will give us errors, but there are a lot of information in google to solve the problems.
sudo apt-get install libgtk2.0-dev
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_EXAMPLES=ON ..
and after that continue the installation of openCV
