It tries to execute a non-executable file... not sure if it's still a
dirty state or a genuine bug... either way, I dropped the source dir
completely.

Please check if you have 'makeinfo'. This script tries to use it and
apparently fails if it is absent.

test -n "$MAKEINFO" && break
done
test -n "$MAKEINFO" || MAKEINFO="$MISSING makeinfo"

case " $build_configdirs " in
*" texinfo "*) MAKEINFO='$$r/$(BUILD_SUBDIR)/texinfo/makeinfo/makeinfo' ;;
*)

# For an installed makeinfo, we require it to be from texinfo 4.7 or
# higher, else we use the "missing" dummy.
if ${MAKEINFO} --version \ # <--- LINE 7993 here!!!
| egrep 'texinfo[^0-9]*(4\.([7-9]|[1-9][0-9])|[5-9]|[1-9][0-9])'
>/dev/null 2>&1; then
:
else
MAKEINFO="$MISSING makeinfo"
fi
