So, I found out that my trustedqsl package is fairly guilty in this
regard. Not in regard to freetype, but it links directly to openssl and
libexpat, even though it doesn't use them. Upstream's autoconf setup
actually does this deliberately.

I've trimmed the configure scripts to avoid this, leaving me with the
link commands for the two binaries being:

g++ -Wall `"/usr/bin/wx-config" --cxxflags` -I/usr/include -I/usr/include -I/usr/include -g -O2  -o tqsl  tqsl.o extwizard.o tqslwiz.o dxcc.o stationdial.o qsodatadialog.o tqslvalidator.o tqsl_prefs.o wxutil.o -pthread -lwx_gtk-2.4 -ltqsllib

g++ -Wall `"/usr/bin/wx-config" --cxxflags` -I/usr/include -I/usr/include -I/usr/include -g -O2  -o tqslcert  tqslcert.o crqwiz.o dxcc.o certtree.o tqslcert_prefs.o getpassword.o extwizard.o loadcertwiz.o wxutil.o -pthread -lwx_gtk-2.4 -ltqsllib

(wx-config --libs says "-pthread -lwx_gtk-2.4").

However, my built package depends on zlib1g, which it doesn't use
directly and doesn't -l during link. 

I'd welcome any suggestions on how this might be... dpkg-shlibdeps bug?
