Hi,

The MariaDB-devel RPM (for 10.2) seems to contain the following 
libraries on Fedora 25:

> $ dnf repoquery -l MariaDB-devel|grep /usr/lib64
> /usr/lib64/libmariadbclient.a
> /usr/lib64/libmysqld.a
> /usr/lib64/libmysqlservices.a
> /usr/lib64/mysql/libmysqlclient.so

> /usr/lib64/libmysqlclient.a
> /usr/lib64/libmysqlclient_r.a
> /usr/lib64/libmysqld.a
> /usr/lib64/libmysqlservices.a

I think it'll work if you use -lmariadbclient instead of -lmariadb.

As the mariadb_config gives the wrong paths, I recommend opening a bug 
report on jira.mariadb.org <https://jira.mariadb.org/projects/MDEV/>.
