[evince/gnome-2-26] [build] Adds -no-undefined flag for Cygwin build

[Nickolay V. Shmyrev <nshmyrev src gnome org>]

commit d18aa4d73c9191da8e867230e287d279d65a7ca0
Author: Nickolay V. Shmyrev <nshmyrev yandex ru>

    [build] Adds -no-undefined flag for Cygwin build
    
    Added flag -no-undefined required by Cygwin for installed shared
    libraries since Cygwin's libtool can't track library dependency
    automatically. Fixes GNOME bug #580058. Patch from Yaakov Selkowitz
    <yselkowitz users sourceforge net>
