Setup Cross compiler

Create an installation on an SDCARD or copy the contents of the raspian image to a new directory. Both will be referred to as 'raspbian' as a mount point

#Mount img

mkdir -p tmp raspbian
sudo mount rasp.img tmp -o loop -o offset=$((122880*512))
sudo cp -rpv tmp/. raspbian/.
sudo umount tmp

#Install to SD Card

sudo dd if=rasp.img of=/dev/sdx bs=8M

#Copy qemu to the raspbian system

sudo cp /usr/bin/qemu-arm-static raspbian/usr/bin

#Chroot and enjoy

sudo LC_ALL=C chroot raspbian
