"configure --help" says:

--with-tiff             use -ltiff for displaying TIFF images

So, "configure --with-tiff=no" does not attempt to use -ltiff for
displaying TIFF images; but if the tiff API is available elsewhere
(e.g., in the C library, or perhaps in some other library that you
specified in LDFLAGS), Emacs uses the TIFF API anyway.  Perhaps that
is what happened with you?

The --with-tiff behavior is consistent with the way that Emacs
configures other libraries (e.g. jpeg).  Perhaps the convention should
be changed, so that --with-tiff=no means "do not use the TIFF API at
all"?  If so, this change should be made consistently for all the
--with options.
