commit 9786e3a96e6772166f3523e74a748b9db20fae7c
Author: Alon Bar-Lev <alon.barlev at gmail.com>
Date:   Tue Mar 28 21:55:59 2017 +0300

    python,build: Reinstate prepare target.
    
    * lang/python/Makefile.am: Fix 'prepare' target.
    * lang/python/setup.py.in: Use 'abs_top_builddir' instead of guessing
    the path.
    --
    
    'prepare' will prepare target at PREPAREDIR.  The automake integration
    will also make use of prepare target.  Downstream distributors may
    also make use of prepare target.
