Comment:

 I don't think that's enough. The new variants don't set the pg_version and
 my_version variables which get reinplaced into src/database/wscript. And
 simply having a variable my_version with a number isn't sufficient to
 express the path for mariadb or percona. Also, as I look at the wscript
 patch in the files directory, it contains hardcoded paths, including a
 hardcoded prefix, which need to be changed to placeholder strings that get
 reinplaced.
