Which is FUD, insomuch as CDBS only handles cross-building for packages that
use GNU autoconf and many cross-building fixes require patching upstream
code.

If you want that to be what the thread is about, kindly don't lead into it
with trolling about CDBS.

I agree. If nothing else, this is relevant because packages which use
autoconf may otherwise mis-optimize for targets other than the default
target for each of our given architectures when not explicitly told the
system type using the dpkg-architecture information.

Note that this is an inherently *non-obvious* change to have to make to
support cross-building, which is why the opacity of CDBS makes it an
incredibly sucky system if you want maintainers who are actually able to
reason about what their packages are doing.
