Source tarball without version info in filename

See https://downloads.mariadb.org/client-native/1.0.0/

Source tarball is named "mariadb-native-client.tar.gz", not including the 1.0.0 version number and not matching the name pattern of all the other download files either

Should either be "mariadb-native-client-1.0.0.tar.gz" or "mariadb_client-1.0.0.tar.gz" to match the name pattern of the other files.

Same for the contained top level directory, that should also be named
either "mariadb-native-client-1.0.0" or "mariadb_client-1.0.0" and not just "mariadb-native-client"
