Bug#913148: libpwquality FTCBFS: issues with python

[Helmut Grohne]

Source: libpwquality
Version: 1.4.0-2
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

libpwquality fails to cross build from source. Its Build-Depends ask for
python-all-dev, but that's a host architecture python. It wants a build
architecture python plus host architecture development headers. In
general, we typically replace python(.*)-dev with "libpython\1-dev,
python\1-dev:any". Then setup.py uses the build architecture compiler.
The method to tell python to cross build is prepending a host specific
path to PYTHONPATH. The attached patch makes libpwquality cross build
successfully. Please consider applying it.
