Bug#920365: [debian-mysql] Bug#920365: Bug#920365: Bug#920365: mariadb_config: improve cross compilation support

[Otto Kekäläinen]

I've removed the multi-arch: same for libmariadbd-dev in
https://salsa.debian.org/mariadb-team/mariadb-10.5/-/commit/173b5ffbd40e448ecc5fc47312fa23ea30e1f0b5
but either way I do it Lintian keeps complaining and I get confused of
what is the final and best solution for mariadb-10.5 on this front.
Merge requests / patches are welcome.
