Really?  Maybe someone could help to draw a real hamburger.

IDK, some programs display it on the left, some on the right.

Anyway, there is a bug in tool-bar code that doesn't allow to use
align-to, whereas align-to works perfectly when used on the tab-bar.

Here is the test case to reproduce the bug on the tool-bar:

emacs -Q and eval:

  (define-key-after (default-value 'tool-bar-map) [global-menu-bar]
    `(menu-item (propertize " " 'display '(space :align-to (- right 5)))
                (lambda ()
                  (interactive)
                  (popup-menu (mouse-menu-bar-map)))
                :image ,(tool-bar--image-expression "newsticker/narrow")
                :help "Pop up the global menu bar"))
  (force-mode-line-update)

It doesn't align the icon to the right edge of the tool-bar
whereas the same code aligns it on the tab-bar.
