I think that makes sense conceptually, but I think that people that do
a --without-x build do so for a particular reason: They want to have as
lean an Emacs as possible.  (Otherwise -- why bother?)

So we could certainly do this (and similarly for a bunch of other
stuff):

diff --git a/lisp/loadup.el b/lisp/loadup.el
index ed1570e778..b7e63cc656 100644
--- a/lisp/loadup.el

 (load "jit-lock")
 
 (load "mouse")
-(if (boundp 'x-toolkit-scroll-bars)
-    (load "scroll-bar"))
+(load "scroll-bar")
 (load "select")
 (load "emacs-lisp/timer")
 (load "emacs-lisp/easymenu")

But I'm not sure we'd be doing anybody any favours.

Does anybody have an opinion here?
