Indeed build IDs can be a very annoying source of unreproducible builds (though I mostly encounter those working with Android toolchains, not Debian packages). But build IDs can be disabled via appropriate linker flags (e.g. -Wl,--build-id=none). Is there some reason simply doing that for both rebuilds is not an option? - Fay
