Thank you Adrian for the patch.

I wonder whether we could circumvent this kind of trouble by adding
architecture-is-64-bit to Build-Depends.  This would mean we need to
ask for removal of quite a number of binary packages, thought.  But
in the end I think this is no practical restriction for our users
and we might get rid of some maintenance burden.

Kind regards
    Andreas.
