Wild guess:

1) Yes, I would think so. mysql/mariadb are known for being memory
hungry monsters that overcommit a lot.

2) Given that mysql/mariadb is started by the package being built,
not by the usual startup scripts (which are disabled by policy-rc.d
inside the chroot), there is a small chance that mariadb could be
started in a way that it uses less memory. I would try searching for
"memory optimizing mysql" or something alike and also look for the
exact place where mariadb is started during the build.

Thanks.
