To display help tooltips in the echo area turn `tooltip-mode' off.
To display GUD tooltips in the echo area turn `gud-tooltip-mode' on and set
`gud-tooltip-echo-area' to t.

This sounds more complicated, but displaying help text in the echo area
shouldn't require tooltips. It a text property like mouse-face. Using
tooltip-use-echo-area invokes tooltip-show with its delays etc
unnecessarily.

In contrast displaying GUD tooltip text in the echo area does require
the gud-tooltip machinery (like track-mouse) because text properties
aren't involved.
