I've attached a patch (against sbuild git master, also on the
cross-build branch of git://git.debian.org/users/rleigh/sbuild.git)
which adds --host and --build options and then uses the correct
host or build arch in the appropriate places.  While I've tested
everything still works fine for normal non-cross builds, this will
need testing for cross builds to make sure I've not got the
host/build arch mixed up in any places (since I will not have
picked any error up when they are both the same).

Roger
