Gitlab fails to compile with MariaDB 10.2
As pointed here https://github.com/brianmario/mysql2/issues/851 there's a problem with mysql2 gems and mariadb. I have updated my gems file to use mysql2 0.4.9 and it works.
Is updating the ebuild something we could consider doing here? This is only needed if the MariaDB version in use is 10.2 or higher.
