Thank you for confirmation.

I examined other emacs built-in libraries to figure out how they
suppress redundant text labels. It seems that there is an undocumented
feature such that non-nil :vert-only property for tool bar specification
does the job. (And I noticed a related topic in emacs-devel archive:
https://lists.gnu.org/archive/html/emacs-devel/2020-09/msg00935.html )

The revised patch is attached below. Now AUCTeX tool bar follows the
user preference even when `tool-bar-style' is customized to `both',
presenting labels under icons. (In that case, "Preview" icon lacks the
label, at least for me. It seems that either emacs or gtk omits the
label text "Preview at point" since it's too long to fit there.)

What do you think about it?
