In a clang-17[default-libcxx] environment, x11-libs/libxklavier-5.4-r1 will fail to link during emerge with the following error message:
```
ld.lld: error: version script assignment of 'global' to symbol 'xkl_engine_VOID__FLAGS_INT_BOOLEAN' failed: symbol not defined
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[3]: *** [Makefile:477: libxklavier.la] Error 1
make[3]: Leaving directory '/var/tmp/portage/x11-libs/libxklavier-5.4-r1/work/libxklavier-5.4/libxklavier'
make[2]: *** [Makefile:408: all] Error 2
make[2]: Leaving directory '/var/tmp/portage/x11-libs/libxklavier-5.4-r1/work/libxklavier-5.4/libxklavier'

make[1]: Leaving directory '/var/tmp/portage/x11-libs/libxklavier-5.4-r1/work/libxklavier-5.4'
make: *** [Makefile:367: all] Error 2
```

This can be avoided by passing "-Wl,--undefined-version" to LDFLAGS.

Attaching logs.

    x11-libs/libxklavier: Remove undefined symbol
    
    Symbol xkl_engine_VOID__FLAGS_INT_BOOLEAN is not defined. Upstream is
    dead per https://www.freedesktop.org/wiki/Software/LibXklavier/.
    
    This change allows libxklavier to build with clang-17 by deleting the
    undefined symbol from the version symbol map.
    
    Despite upstream status, the following packages still depend on
    libxklavier:
    
        app-accessibility/caribou
        dev-libs/eekboard
        dev-libs/input-pad
        gnome-base/libgnomekbd
        gnome-extra/cinnamon-control-center
        gnome-extra/cinnamon-settings-daemon
        mate-base/libmatekbd
        mate-base/mate-control-center
        mate-base/mate-settings-daemon
        mate-extra/mate-screensaver
        x11-misc/lightdm
        xfce-base/xfce4-settings
        xfce-extra/xfce4-screensaver
        xfce-extra/xfce4-xkb-plugin
