commit 1607aa7fe5dd686ba3bfb6de4a2b602d6a458c86
Author: Justus Winter <justus at g10code.com>
Date:   Wed Jun 1 15:33:52 2016 +0200

    python: Make Python detection more robust.
    
    Previously, missing Python development packages made configure fail
    instead of merely disabling the bindings.
    
    * configure.ac: Check for 'PYTHON_VERSION'.
    * m4/ax_python_devel.m4: Make test non-fatal.
