Cross compiler for OF 0.9.0/Jessie/arm6/RPi1

I would try removing the lines and see what happens if you try and compile OF.

clean it first

make clean -C /media/Data/home/pi/openFrameworks/libs/openFrameworksCompiled/project

and then

make -C /media/Data/home/pi/openFrameworks/libs/openFrameworksCompiled/project

If you get the same errors try doing the RPI_ROOT copying process again.
