I’m not sure if you’ve tried it lately, but it does show this on my side. I
see it from time to time I do a run through the book because I sometimes
pass the options to make the build generic (which are documented in the
book). We should update the note prior to -rc1.

As a reminder, the auto detection for GMP isn’t perfect, and if you don’t
pass it and know there is a chance you’ll run it on a separate system with
a different CPU micro architecture level or vendor, you are in for a real
world of hurt between this package and libffi. You get a pretty quick
kernel panic after systemd crashes due to an illegal instruction in libffi
:)
