    build: replace intltool with gettext
    
    Gettext, since version 0.19, provides infrastructure equivalent to
    intltool (generating po/Makefile and translating .desktop files or .xml).
    
    Also, it seems to work better in that it actually honors MSGFMT_OPTS
    that are determined by the configure script. That one typically ends up
    set to "-c", meaning "check". Without it the bugs in the .po files are
    easy to overlook.
