Cool. My build environment must be buggy then.

In any case, this change makes cross building mariadb a lot easier.

I fear that there is little you can do here. The hinter likely told you
that you can mark libmariadb-dev-compat Multi-Arch: same. Lintian told
you that Multi-Arch: same is useless since libmariadb-dev is not thus
marked. Both are correct. The idea of the hinter is that by
parallelizing the addition of M-A:same, we get everything marked quicker
while having some useless (but correct) markings in the interim. The
lintian stance is that useless markings issue a warning.
