Subject: [PATCH] python: make remaining scripts use /usr/bin/env

Unfortunately there is no concept of a host python vs. target python
to facilitate cross compilation. There is only one PYTHON variable and
this is used during building and in the header of python scripts after
installation. The best approach for cross compilation is to thus to
ensure python is in the path and avoid passing a path as part of
PYTHON. To make this function smoothly all installed scripts should
make use of /usr/bin/env to increase the chances of finding python.
