I understood, but I think it isn't needed even once, because we don't
care about the exact command unless we run into some trouble.

The command is quite long, so outputting it even once will write a lot
of stuff to the screen, stuff that we almost always ignore.

It's a general Autoconf-based solution many/all GNU projects use, so
if we want to change that to something more memorable, we should
change that across the board.

(FWIW, I keep notes in a prominent place about important stuff I'm
likely to forget due to rare use.)
