In a clang-17[default-libcxx] environment, media-libs/libpulse-16.1-r2 will fail to link during emerge with the following error message:
```
ld.lld: error: version script assignment of 'PULSE_0' to symbol 'pa_glib_mainloop_free' failed: symbol not defined
ld.lld: error: version script assignment of 'PULSE_0' to symbol 'pa_glib_mainloop_get_api' failed: symbol not defined

clang: error: linker command failed with exit code 1 (use -v to see invocation)
ninja: build stopped: subcommand failed.
```
This can be avoided by passing "-Wl,--undefined-version" to LDFLAGS.

    media-libs/libpulse: Fix build with lld
    
    Pulseaudio uses the same linker version script for all library variants,
    so a few symbols remain undefined for some variants. This breaks buid with new
    lld which defaults to errors with undefined symbols in linker version scripts.
    
    Fix this by adding -Wl,--undefined-version to linker flags.
