readlink: document portability issue with symlink length Per comments in areadlink, ERANGE on a too-small buffer is expected on some platforms; making the readlink module guarantee GNU behavior of truncated contents is counter-productive, since we would be duplicating areadlink to learn a-priori how large to make the buffer, and since truncated contents are not as useful. * doc/posix-functions/lstat.texi (lstat): Mention that some file systems have bogus st_size on symlinks, and mention the areadlink-with-size module. * doc/posix-functions/fstatat.texi (fstatat): Likewise. * doc/posix-functions/readlink.texi (readlink): Mention the areadlink module, and ERANGE failure. * doc/posix-functions/readlinkat.texi (readlinkat): Likewise. * tests/test-readlink.c (main): Relax test for AIX, HP-UX.
