I audited the utils and tests and the following programs where your
patch adds libpulsecore only use functionality from libpulse and
libpulsecommon:
pacat, pactl, pasuspender, pacmd, pax11publish, mainloop-test, voltest
libpulsecore should not be added for these, because they don't use
functionality from that library. Your output log from above suggests
that something in libpulsecommon uses functionality from
pulsecore/object.[ch], so those files should probably be moved to from
libpulsecore to libpulsecommon. Does that fix linking on Solaris?

The rest of the utils only use public libpulse headers, so for these
libpulsecommon should even be removed from the linker line.
