Cross-compile node.js for Raspberry Pi

rpi-node.sh

#!/usr/bin/env bash

# Based on https://github.com/needforspeed/Nodejs-ARM-builder/blob/master/cross-compiler.sh
# but updated to use the cross-compiling tools that Raspberry Pi recommends for the kernel.
# Only works for ARMv6.

# AJJ: Released into the public domain.
