Subject: [PATCH] Fix build without Python

Don't define HAVE_PYTHON35 when PYTHON_LIBS is empty.

Also, don't build Python dependent code when HAVE_PYTHON35 is not
defined.

This fixes build failures like:

Makefile:1616: recipe for target 'python-pkg/dist/lirc-0.10.0.tar.gz' failed
make[3]: *** [python-pkg/dist/lirc-0.10.0.tar.gz] Error 1
python-pkg/lirc/_client.c:1:20: fatal error: Python.h: No such file or directory
 #include <Python.h>
                    ^
