Turns out that there is.  After careful reading of the Elisp reference and 
"mouse.el", and some experiments, I figured out that it's just a matter of 
defining the menu in a special way.

The top menu bar will only show items that have no special key attached to the 
"[menu-bar]" binding, whereas the minor mode lighter simply shows the entire 
menu in the minor mode map.

Hence, creating a menu with "easy-menu-create-menu", and binding it as "[menu-
bar flycheck]" in the mode map does the job.

https://github.com/flycheck/flycheck/commit/b727e98fcbdfd27f4dc2ebe0777ec888192973d0
 
has the corresponding change, for reference.

Many many thanks for your help.  Without your pointer to "mouse-minor-mode-
menu" and "minor-mode-menu-from-indicator" I'd never have been able to figure 
it out.
