[etherlab-users] Cross Compile for ARM

[Andreas Stewering-Bone]

Hello,

In my setup I build a complete kernel for the beaglebone board. Attached 
you find a script to compile the kernel and modules, install it on a 
MM-card, compile the master, install the modules an userland.

Please try.

#get Beagleboard stuff
#git clone https://github.com/beagleboard/kernel.git

#define local git repo to prefend getting huge vannilla git repo twice
