I think you just give people a very simple rule: build your binaries on
the oldest version of the OS you want to support.

That always works, unless back compat is broken, but in principle back
compat should never be broken and most people agree with that principle.

No black magic there.

It would be nice to have some way to give an error message like "this
binary was compiled with version 4.0, so can't run on 3.0" instead of
the obscure link errors, of course.
