Looks good, applied to git, thanks.  It doesn't appear to do
anything in Debian at present (build_arch, that is) or at least
it's not documented to work, but doesn't appear to break anything.

BTW, would it be helpful for you to be able to work on sbuild
directly?  You would be welcome to join (buildd-tools-devel on
alioth).
