Noted. You might want to mention this in the footer at
http://crossqa.debian.net/

Thanks Helmut for the advice!

If one of our contributors (Faustin? Tuukka?) can file an MR at
https://salsa.debian.org/mariadb-team/mariadb-server/-/merge_requests
with suitable code for dumping the header as Helmut suggested, I can
upload it to Launchpad (which has both 64 and 32 bit builders and both
endianness) so we can see the result in the logs, and if needed I
could also include that in the next Debian experimental upload.
