Do not look for pg_config, mysql_config in PATH when cross-compiling

Otherwise it can happen that we pick up the tool for the host system,
which will break compilation.

Users can still pass
 -psql_config /path/to/pg_config

or
 -mysql_config /path/to/mysql_config

manually.

[ChangeLog][QtSql] When cross-compiling pg_config, mysql_config
are not looked up in PATH anymore. Pass -psql_config path/to/pg_config
or -mysql_config path/to/mysql_config to explicitly enable PSQL or
MySQL in this setup.
