pulseaudio: Fix build with LLD linker

LLD is stricter with version scripts
This is a classic LLD vs GNU ld compatibility issue with
version scripts. LLD is stricter than GNU ld — by default
it treats unmatched version script symbols as hard
errors, whereas GNU ld silently ignores them.

What's happening is that the version script
e.g. map.pa, declares symbols like pa_glib_mainloop_new
under PULSE_0, but those symbols aren't being compiled
into the current library target.
