  Fix canonicalize loop-detection corner case.
  
  Do not attempt to stat the symlink values stored via seen_triple.
  Without this, coreutils' tests/misc/readlink-fp-loop test would fail
  on linux-2.6.18, (but not 2.6.22).
  * lib/canonicalize.c (seen_triple): Use triple_compare_ino_str, not
  triple_compare.  The former compares dev,ino,filename, while the latter
  would actually stat dirname(filename) when dev and ino were equal.
  * lib/hash-triple.c: Install <string.h>.
  (STREQ): Define.
  (triple_compare_ino_str): New function.
  * lib/hash-triple.h (triple_compare_ino_str): Declare it.
