lisp/makefile.in edit needed for --no-cygwin build

[David Abrahams]

Trying to rebuild NTEmacs today using MinGW I found that I needed to replace:

        $(EMACS) $(EMACSOPT) -l autoload --eval '(setq generated-autoload-file 
"$(lisp)/loaddefs.el")' -f batch-update-autoloads $$wins

with

        $(EMACS) $(EMACSOPT) -l autoload --eval '(setq generated-autoload-file 
"./loaddefs.el")' -f batch-update-autoloads $$wins

The absolute windows pathname in $(lisp) seemed to be confusing emacs.

This change would be posted as a patch, but I didn't actually test a
change to makefile.in; I edited the generated makefile to make things
work.
