It doesn't give a different result, per se, but it is a more correct way
of doing things.  IMHO, DESTDIR is a hack best reserved for things which
aren't using autoconf/automake since it's so trivial to do things with
automake and autoconf.  

I also seem to remember hitting weirdness with shared libs and getting
odd rpaths compiled in when using DESTDIR but that's less of a problem
with OpenAFS :)
