LIBSSH_OBJS is used to build the libssh.a library.  SSHOBJS and SSHDOBJS
are used to build the ssh and sshd binaries.

Below is two lines to insert into your Makefile.in which should ensure
that all ssh and sshd objects are recompiled on changes in config.h, but
that still leaves all the other commands (ssh-keygen, ssh-keyscan,
etc) with potentially out of date object files.  

-- Add on Makefile.in after $(LIBSSH_OBJS): config.h line --
$(SSHOBJS): config.h
$(SSHDOBJS): config.h
-- Snip ---

I strongly suggest doing a 'make clean' after any new ./configure (or
change to config.h) to ensure that all object files are up to date.
