Multiarch-hinter says: libmariadbd-dev conflicts on
/usr/include/mariadb/server/my_config.h on any two of amd64, arm64,
armel, armhf, and 5 more

I don't understand this, since my_config.h is supposed to be an ASCII
file and identical to all archs.

Running in Debian unstable to verify the file contents:

apt install libmariadbd-dev
cat /usr/include/mariadb/server/my_config.h
