If I would knew what could happen I would be specific about it. Frankly, I
don't know. It might be all fine to dpecify --build and --host all the
time, even if not cross compiling. It might be fine with all package from
some specific autoconf on. If it happens, it will likely be a bug in the
packages configure.in or so. I don't think it would be all too bad to try
it out and see what breaks (and fix that), but I feel more comfortable if we
have some safebelts to offer in case of the unexpected.

See my other reply, where I offer three alternatives. It turns out that
your suggestion will work best, as it works for all versions of autoconf.
I also have developed a "smart" version for autoconf 2.13 and one for
autoconf 2.52 (and later).
I think it is reasonable to use your approach of specifying both by default,
but keeping the smarter alternatives around for people who want or need
them.

Yes, this is very useful. Search for all occurences of "dpkg-architecture",
the DEB_ variables involved, and for --print-architecture,
--print-installation-architecture and --print-gnu-build-architecture. Those
three latter options are quite obsolete except for backward compatibility
fallback solutions, and it would be nice to have the raw data where they are
still used (if you don't want to fix those packages as well, send the data
to me, please).
Thanks,
