Enable ability to build for Arduino with debug enabled.

Enable ability to build for Arduino with debug enabled.

The changes in this commit were required because for some reason the
function to log out a buffer's value was fully commented out for
the Arduino platform, while calls for it still existed for the Arduino
platform when running in debug mode.
