Hi,

yes, to do a comparative rebuild, I just need such a script that adjusts
the build environment to whatever is needed. See other examples in
https://salsa.debian.org/lucas/collab-qa-tools/-/tree/master/modes

I have a few rebuilds to run and process, and little time for Debian
currently, but I'll find the time eventually.
