I'm a little puzzled as to why my patch made it cross build. Your
observation seems entirely correct.

In any case, I don't think that we will release bullseye with Python
3.7.

So even if the patch means that gpgme cross builds python3-gpg without
support for 3.7, I think that's a reasonable compromise when comparing
maintenance cost vs. features. I suppose that the majority of cross
build users would want the C library and not the Python bindings. Once
3.7 is removed, the issue "heals" itself, so I suggest not spending time
on it.

Does that work for you?

If Python continues to be annoying, I'd propose the addition of a
<!nopython> profile to reduce the scope of cross builds.
