    Manually link with libiconv whenever we use libintl.
    
    Sadly our Windows libintl DLL doesn't convey that it should pull in libiconv
    as a dependency (nor does it use pkg-config). Until I figure that out, let's
    just manually link with libintl when needed.
    
    There is also some hacking of gconvert.c and the toplevel meson.build file
    needed to adjust the build system -- it assumes that on Windows you're always
    going to use an internal iconv.
