It seems that your openssl libraries do not automatically pull in the
libdl library when you link with it.

As a workaround, you can change build/Makefile.test-ssl: The "test-link"
command reads
   @$(CC) $(CFLAGS) $(OSSLLIB) -o test-ssl test-ssl.o -lssl -lcrypto $(NETLIBS)
Add a "-ldl" after the "$(NETLIBS)".

That should allow the configure script to complete. After that, you must
change the top-level Makefile: It has a line with
   SSLLIBS = -L/usr/lib -lssl -lcrypto
Change that to
   SSLLIBS = -L/usr/lib -lssl -lcrypto -ldl
