Because the autotools stuff automatically uses g++ to build a *.cpp
file, and addon-dell-backlight.cpp actually uses dynamic_cast,
namespace, and other C++ features.

Maybe the more correct fix is to change the file to only use C, but
that's more invasive, and might not be desired in the first place.

Thanks,

Martin
