[Debian-astro-maintainers] Bug#873690: ginga: don't hard-code python versions in debian/rules

[Steve Langasek]

Package: ginga
Version: 2.6.5-1
Severity: important
Tags: patch
User: ubuntu-devel at lists.ubuntu.com
Usertags: origin-ubuntu artful ubuntu-patch

ginga sets PYTHONPATH in order to call the program locally for help2man. 
But even though debian/rules uses py3versions and already has a $(PYTHON3)
variable available for use, the PYTHONPATH is hard-coding python3.5.

This will become a build failure when Debian transitions to python3.6, which
is due to happen sometime soon this cycle.

Attached is a patch that fixes this latent bug.

Thanks,
