Can you really expect tools like Autoconf to break hard links in this
situation? Most POSIX utilities are required to leave output files
hard-linked, so there's good precedent for Autoconf's behavior. Even
if we altered Autoconf, that still leaves the sh, cp, etc. as tools
that won't break the hard links.
