It's not clear to me whether you mean --without-x builds or --with-x
builds started with -nw (or both), but in either case:

In a with-x build:
emacs -Q -nw

C-h f tool-bar-mode
 tool-bar-mode is an interactive compiled Lisp function in `tool-bar.el'.

C-h f set-scroll-bar-mode
 set-scroll-bar-mode is a compiled Lisp function in `scroll-bar.el'.

(tool-bar-mode 1)             ; no error

(set-scroll-bar-mode 'left)   ; no error


In a without-x build, neither tool-bar-mode nor set-scroll-bar-mode is
defined.

Thus, I see no inconsistency here and don't understand your request.
