alsa-project/alsa-lib issue #356 was edited from parona-source:

LLD 17 defaults to erroring out on undefined symbols in version scripts.

``` libtool: link: clang -m32 -mfpmath=sse -shared -fPIC -DPIC .libs/conf.o .libs/confeval.o .libs/confmisc.o .libs/input.o .libs/output.o .libs/async.o .libs/error.o .libs/dlmisc.o .libs/socket.o .libs/shmarea.o .libs/userfile.o .libs/names.o -Wl,--whole-archive control/.libs/libcontrol.a mixer/.libs/libmixer.a pcm/.libs/libpcm.a timer/.libs/libtimer.a rawmidi/.libs/librawmidi.a hwdep/.libs/libhwdep.a seq/.libs/libseq.a ucm/.libs/libucm.a -Wl,--no-whole-archive -Wl,--as-needed -lm -lpthread -lrt -m32 -mfpmath=sse -O3 -march=znver3 -Wl,--version-script=Versions -Wl,-z -Wl,defs -Wl,-O1 -Wl,--defsym=__gentoo_check_ldflags__=0 -Wl,-soname -Wl,libasound.so.2 -o .libs/libasound.so.2.0.0 x86_64-pc-linux-gnu-ld: error: version script assignment of 'ALSA_0.9.5' to symbol 'alsa_lisp' failed: symbol not defined x86_64-pc-linux-gnu-ld: error: version script assignment of 'ALSA_1.2.10' to symbol 'snd_seq_seq_client_info_get_ump_group_enabled' failed: symbol not defined x86_64-pc-linux-gnu-ld: error: version script assignment of 'ALSA_1.2.10' to symbol 'snd_seq_seq_client_get_ump_conversion' failed: symbol not defined x86_64-pc-linux-gnu-ld: error: version script assignment of 'ALSA_1.2.10' to symbol 'snd_seq_seq_client_info_set_ump_group_enabled' failed: symbol not defined x86_64-pc-linux-gnu-ld: error: version script assignment of 'ALSA_1.2.10' to symbol 'snd_seq_seq_client_set_ump_conversion' failed: symbol not defined clang: error: linker command failed with exit code 1 (use -v to see invocation) ```

These symbols were added in https://github.com/alsa-project/alsa-lib/commit/2aefb5c41cc03b72b3161b57336d..., the subsequent commits makes me think these could be symbols that were added prematurely and that there is an intention to implement them. Which is why I am making an issue instead of making a pull request removing them.

@tiwai any input on this?
