Bug#818400: Built plugin from source

[Sebastian <sebastianspublicaddress@googlemail.com>]

Dear Maintainer,
when I build the plugin from source like this:

apt-get source gcc-python3-plugin
cd gcc-python-plugin-0.15/
sudo apt-get install debhelper dh-python gcc-5-plugin-dev g++-5 python3-all-dev python3-all-dbg python3-lxml python3-pygments python3-six python3-sphinx
make  PYTHON=python3  PYTHON_CONFIG=python3-config  all

I am not sure if this is the correct way to build for debian - I just saw this example in the Makefile and tried.

I get these from the build:

Failed tests:
  tests/cpychecker/refcounts/PyDict_SetItem/correct
  tests/cpychecker/refcounts/PyDict_SetItemString/correct

  tests/cpychecker/refcounts/object_from_callback
  tests/cpychecker/refcounts/ticket-20

But the plugin still works when called like this:

./gcc-with-python ../../bugreport/script.py ../../bugreport/sourcefile.c -c -o tmp.o
rm tmp.o
