[PATCH] gnu: mariadb: Split into out, lib and dev.

> This patch splits mariadb into three parts: out (150 MB), lib (38 MB)

> and dev (5 MB). This means that dependents now have a lighter closure.

>

> For instance, python-mysqlclient lost its references to gcc, perl,

> jemalloc and one zlib reference. It went from 537.2 MiB to only 230.4

> MiB. qtbase went from ~1.3 GB to ~1.0 GB.

> I've rebuilt most of these direct dependents without issues, so I don't

> expect any issue with this patch. However, since qtbase is in the

> dependency graph, there are ~500 packages that need to be rebuilt, so

> this patch qualifies for staging.
