This is because lld 17 defaults to errors when undefined symbols are refere=
nced
in linker version scripts. Since pulseaudio uses the same linker version sc=
ript
for both the regular libpulse.so, and the other variants,
libpulse-mainloop-glib.so and libpulse-simple.so, some of the symbols are
expected to be undefined, so suppress the errors by adding
-Wl,--undefined-version to LDFLAGS.
