"devel" mode: IMPORTANT POLICY CHANGE: perl* and python* mapped to target_root

- Changed default mapping of perl* and python* to target_root:
  Prefixes /usr/bin/perl* and /usr/bin/python* are now mapped to
  the rootstrap.
- Previously these scripting languages were used from tools_root
- Script interpreter mapping policies have been set up so that
  a script which is executed from tools_root will take the interpreter
  still from tools_root => there are many tools that are written as
  scripts (for example, many of the dpkg-* tools are perl script),
  so these continue to run with the correct libraries
- Obviously, this has some performance penalties when building for
  a foreign architecture, because the default script interpreter would
  be running under CPU transparency. However, that penalty appears to
  be quite minimal (average result, at least)
