Yes, the format statements are supposed to be there: (@ (guix build 
gnu-build-system) configure) prints the same messages. The code is 
unchanged from the chez-scheme configure phase, just factored out 
because we will also need it for cross-compiling 
chez-scheme-for-racket-bootstrap-bootfiles (because there's now a 
supported way to do that, and the experimental script we'd been using 
had bit-rotted) and for chez-scheme-bootstrap-bootfiles (native and 
cross) once we start bootstrapping it.

I had intended to put it here, but your comment prompted me to rethink 
it. For context, the build-docs phase is new in this commit: previously, 
I relied on the fact that the install-docs target depends on build-docs. 
I now think I should move the first line of the comment to build-docs 
and add a comment to install-docs pointing that out, because its part of 
the issue with cross-compilation. (Currently, the build scripts try to 
use the cross-compiled scheme to build the docs, which obviously doesn't 
work. The Right Thing would be to build the docs using the native scheme 
while using the sources from the cross-built scheme.)

Thanks,
Philip
