The gcscontrolgadget expects all gamepad devices to have
at least 4 axes of control. The SDL layer (on Linux anyway)
will detect the accelerometer that's built into some laptops
as a gamepad with 3 axes.
This change prevents the accel from being selected and
subsequently flooding the console with errors from
gcscontrolgadget every 10ms.
This will allow us to build a parent project for
qt-creator that sits above both openpilotgcs and
uavobjgenerator so that we can build both projects
at the same time.
