Setup armv7h chroot under x86_64 host (Archlinux/Archlinuxarm biased)

Simple way to setup an arm chroot for building packages for your arm devices. This is an alternative to cross-compiling where you are limited to only linking against the libs in your toolchain.

Setup chroot-fs

You can store the chroot wherever you like. I choose to store it in a disk-image which I mount to my filesystem.
