Hello,
I asked libtool at gnu.org, the answer is that yes libtool 2.2.4
will by default place the LDFLAGS options before the libraries
in the build directories when doing "libtool -relink" during
"make install". So the default behaviour is that libtool could
find some old, incompatible libraries in the directories
listed in the -L options in LDFLAGS, which could then result
in "Undefined symbol" errors.
The workaround for the libtool -relink problem is simple though,
I manually added a -L option for the pkgbuild directory at the
front of LDFLAGS before the configure and build, so that the
make install finds the just installed libraries before the
libtool -relink, like:
goanna% svn diff Dude/TAGLIB/1.5.0/Solaris/configure.sh

+# libtool 2.2.4 relink looks for libs first in LDFLAGS. Placing

./configure --prefix=${PREFIX} \
--bindir=${_bindir} \
--sbindir=${_sbindir} \

Then it links fine, and the rpath is OK:
goanna% dump -Lv /opt/foss/lib/libtag_c.so | grep RUNPATH
[13] RUNPATH
/opt/foss/lib:/opt/foss/lib:/usr/lib:/opt/SunStudio12/SUNWspro/lib/rw7:/opt/SunStudio12/SUNWspro/lib/sse2:/opt/SunStudio12/SUNWspro/lib:/opt/SUNWspro/lib/sse2:/opt/SUNWspro/lib:/usr/ccs/lib:/lib:/usr/lib
