Don't generate empty manual pages when config.sub/config.guess files are updated in distribution tarball and help2man is not installed; don't fail either.
Resist on not 'touch'ing the old pre-generated manual page to not hide the problem, however. Also for git builds stay fatal and enforce help2man installation; just to avoid generating broken distribution tarballs.
