auto-mode-alist can contain any function, so you could get away with
this:

  (defun log-mode ()
    ;; You may want to call `fundamental-mode' or some other mode here
    (setq truncate-lines t))

  (add-to-list 'auto-mode-alist '("\\.log\\'" . log-mode))



If you want to make a proper mode:

  (define-derived-mode log-mode fundamental-mode "Log"
    ;; The mode runs `log-mode-hook', so you could use that instead.
    (setq truncate-lines t))

auto-mode-alist as above.
