Currently only desktop opengl is supported for the waveform rendering, but the odroid only supports opengl es2 so running a binary of mixxx segfaults on the wave render, while attempting to build from source goes great until you hit the waveform rendering code at which point we fail on the build of the shader code.

This would help to also make mixxx portable to android/qt as android only supports opengl es2.
