 or by using e.g. debian armel packages a la cross-debootstrap
(rootstock under the dreaded ubuntu), that gets you into a position
where each of those dependencies can be replaced one at a time.

 ... where is all this documented?

 has anyone actually done this - documented and automated e.g. how the
debian-armel port was created, when previously there was only the
debian-arm one?

 because it really does make sense to have a way to do automated total
recompiles for e.g. the cortex a8, and if debian won't "officially"
add that as an architecture, at least having a well-documented and
automated process by which a random person can just... set some
machines compiling for a month, would be good.
