in repository wine.

commit 2a0aa03dcc269799ef4d9bfd64da1fa0259b6a54
Author: Jens Reyer <jre.winesim at gmail.com>
Date:   Mon Jun 6 04:05:32 2016 +0200

    Generate list of used shared libraries.
    
    First check for all sonames that were found by configure in
    include/config.h. Drop not wanted ones (netapi) and use this list
    for "Recommends". Select some important libraries, which were
    already depended upon before (fontconfig, freetype and ncurses)
    for "Depends".
    
    Then for each set of sonames use sonames2elf to build an ELF
    binary that depends on them, and use dpkg-shlibdeps to compute
    the dependencies and add them to libwineVERSION.substvars
    (dlopen:Depends and dlopen:Recommends}.

     - Change version string to display vendor and version.
     - Drop obsolete dh_strip exclusion of some files.
     - Drop obsolete dependency on x11-utils.
