FYI: make install and ln

[Alexandre Duret-Lutz]

I'm checking in this on HEAD and branch-1-6.

2002-06-26  Alexandre Duret-Lutz  <address@hidden>

        * configure.in: Check that ln works, fall back to `cp -p'.
        * Makefile.am (install-exec-hook): Use $(LN) instead of ln.
        Reported by Andreas Buening.
