branch_release-1-8 not building

[Neil Jerram]

Fails very quickly in ./autogen.sh (see output below), I think because
of these lines in autogen.sh:

cp -f config.guess config.sub build-aux/
cp -f config.guess config.sub guile-readline/

and because of [0].  Are those lines - which were added by [1] - just wrong now?
