Cross instructions

These instructions cover:

1. building a cross toolchain
2. populating the new ROOT
3. making it chrootable using qemu-user to easily run "native" builds or tests (this is like a stage3 at the end)

You do not need to follow through to the end if you don't need a stage3-like root.

Set up the toolchain

# 30 minutes Lisp in Ruby
# Hong Minhee <http://dahlia.kr/>
#
# This Lisp implementation does not provide a s-expression reader.
# Instead, it uses Ruby syntax like following code:
#
#     [:def, :factorial,
#       [:lambda, [:n],
#         [:if, [:"=", :n, 1],
#               1,
