Subject: [PATCH] CONFIGURE: allow to pass specific python version

This is useful if distros support installing multiple python versions
in parallel such as: 2.5, 2.6, 2.7.
For python3.* we will get syntax error during the imports, so the checks
will successfully disable it.
It defaults to python2.
