    build: patch to configure libwmf with no freetype-config.
    
    libwmf was still relying on a script called freetype-config instead of
    using standard pkg-config. It seems it got wiped out in recent freetype2
    (or at the very least, this script is not present anymore in freetype2
    version 24.0.18 from master runtime of GNOME SDK).
    This patch uses pkg-config in libwmf configuration instead.
    
    As I also had some autoheader "missing template" warnings (which were
    failing the recreation of config scripts), I add placeholder
    descriptions to AC_DEFINE() macros, as this is apparently now mandatory.
