• Added checks for CC or CXX env variables in order to build the right output files for arm computers.

I was able to compile on Ubuntu 14.04 by running:

sudo apt-get install gcc-multilib
sudo apt-get install gcc-arm-linux-gnueabihf
arm-linux-gnueabihf-gcc -v
sudo apt-get install g++-arm-linux-gnueabihf
export CC=arm-linux-gnueabihf-gcc 
export CXX=arm-linux-gnueabihf-g++
npm install

I will transfer the resulting binary to Braydon's Pi as soon as I get access. If not, then I will bring in a spare Pi, EDIT: this is done...you can log in to the raspberry pi at 10.10.10.90 and test it out for yourself as well.
