The Debian patch section for Dante showed that they patch ./configure to
use the platform libtool instead of the one shipped with Dante. That's
what I ended up doing also.

$ gsed -ie 's,^LIBTOOL=.*,LIBTOOL=/opt/csw/bin/libtool,' \
	work/solaris8-sparc/build-isa-sparcv8/dante-1.2.0/configure
$ grep ^LIBTOOL= \
 	work/solaris8-sparc/build-isa-sparcv8/dante-1.2.0/configure
LIBTOOL=/opt/csw/bin/libtool

The problem went away. There still is a downrev libtool in $(WORKSRC)
which seems to get re-generated by ./configure, but looking at the build
logs its the /opt/csw/bin/libtool which now takes care of the linking.
