Frederik Rietdijk f665828fa3 Python: improve cross-compilation
This changeset allows for cross-compilation of Python packages. Packages
built with buildPythonPackage are not allowed to refer to the build
machine. Executables that have shebangs will refer to the host.

Frederik Rietdijk d68aba4cfb Python: script names now include full path
Certain programs, like zim, calibre and now also apparently mercurial,
rely on sys.argv[0] providing not just the script name but the full
path.

The Python docs [1] state the following on the matter:

> argv[0] is the script name (it is operating system dependent whether
this is a full pathname or not).

Therefore, scripts should not expect to receive a full path.
Unfortunately some do. While this can be considered a bug, there doesn't
seem any reason not to provide the full path. Therefore we now provide
the full path.
