 `Homebrew` bug report given in #51245. This seems to have been thought of
 because `configure` repeatedly reports the use of that debugging format.

 Now, *this* looks interesting:

 So the new C++ compiler from `stage 1` is going to use another debugging
 format. Building of `stage 2` has started without particular bootstrap
 debugging, but `-gtoggle` gets used.
