Create a local copy of the scripts directory.

The idea is to move the build system out of the project tree as much as
possible. This has two benefits:
 - it does not add any baggage to somebody who just wants to compile the
   project, and doesn't want to create any new modules,
 - it means that project trees don't have to be updated every time a
   change is made to the module instantiation stuff.
