Makefile for crosscompile environment

[MartinVoelz]

Hello, I made changes to your Makefile to make it usable in a cross-compile environment for example the setup from RobertCNelson. (Using conditional variable assignment ?= )

Usage (in bb-kernel dir): git clone https://github.com/cdsteinkuehler/beaglebone-universal-io cd beaglebone-universal-io export FIRMWAREPATH="../KERNEL/lib/firmware" export PREFIX="../KERNEL/usr/bin" make make install

Patch:

Any chance you can send this as a pull request? If not, I'll extract the patch and apply with an appropriate commit message.
