This fixes a bug I inadvertently introduced to Gnulib when I merged glibc glob back into gnulib on 2007-10-16. This fix is inspired by a patch proposed for glibc by Adhemerval Zanella in: https://sourceware.org/ml/libc-alpha/2017-08/msg00446.html * doc/posix-functions/glob.texi: Update list of affected platforms. * lib/glob.c (__lstat64): New macro. (is_dir): New function. (glob, glob_in_dir): Match symlinks even if they are dangling. (link_stat, link_exists_p): Remove. All uses removed. * lib/glob.in.h (__attribute_noinline__): Remove; no longer used. * m4/glob.m4 (gl_PREREQ_GLOB): Do not check for fstatat. * modules/glob (Depends-on): Remove dirfd. * modules/glob-tests (Depends-on): Add symlink. * tests/test-glob.c: Include errno.h, unistd.h. (BASE): New macro. (main): Test dangling symlinks, if symlinks are supported.

work correctly on huge directories larger than 2 GB.
