Help with Mroonga to finally get all of MariaDB Server reproducible

[Otto Kekäläinen]

Hello!

We still have one issue in MariaDB to solve to have the whole package
fully reproducible:
https://tests.reproducible-builds.org/debian/rb-pkg/experimental/amd64/diffoscope-results/mariadb-10.5.html

Chris Lamb looked into this in Feb 2020[1]  and we added one patch[2]
but it wasn't enough. Upstream developer is very responsive (replying
within a day[3]) but unfortunately nobody has managed to track down
where the DYNSTR thing comes from.

Please help! :)

Note that the package is MariaDB Server in Debian[4], that includes
Mroonga[5] which in turn includes Groonga[6]. So there is a chain of
upstreams here to deal with. Groonga exists in Debian also as an
independent package, and it is not reproducible[7] either and it has
different and much more issues than the Mroonga build. I think the
best place is to discuss in the Mroonga Github issue[3].

There is also a Debian bug[8] open on this, but it has no additional info.
