The cause for the behavior seems to be that the mysqli/config.m4 file
checks your the information provided by the "config" program you
passed, but for feature check uses the hard coded name of libmysql.
Maybe this could be refactored to a simpler version check and
discontinue support for versions before 5.0 ... if you send me the
output from 
    mariadb_config --libs
and
    mariadb_config --version
I can see if I can cook up a patch.


That said: Preferred way is to build using mysqlnd instead of libmysql,
so just use  --with-mysql and --with-pdo-mysql without path (or, in
case you like it explicit, =mysqlnd for both) that's the client library
optimized for PHP.
See http://php.net/manual/en/mysqlinfo.library.choosing.php


Also mind that MariaDB is a downstream fork of MySQL and both systems
are diverting and likely will divert more over time. Experience can
vary.
