So you are saying the Debian build system would build a package for an
older release, on a system that is newer, and that build would be
determining things based on the system it is built on, not what it is
being built for?

If so, then something is very broken already in the Debian build system
and I think you have much bigger problems to worry about right now.

For all other "sane" build systems that I know of, you build against the
libraries/kernel/gcc/glibc/etc that you are wanting to support it for,
not against some random-whatever-happened-to-be-installed-on-the-box.

No, you have described a broken setup.

Now for new releases, yes, something might have to be changed, but that
is when a sane distro would move to the newly named kernel, not
affecting any old releases at all.

Hope this helps,
