If you have several Emacsen installed in parallel, the step in 'make
install' that links $(FULLEMACS) to $(EMACS) is almost never wanted.  It
would be nice if there was a separate target that avoided removing the
previous link (which should be left alone) and then creating a new link.

Two patches to Makefile.in (one for trunk and the other for emacs-24)
are attached that implement the above suggestion.  Feel free to give
those targets better names.
