commit 193f1e81edd6b1b56b0eb0ff8aa4b41c7b4257b4
Author: Paul Eggert <eggert@cs.ucla.edu>
Date:   Sun Sep 24 09:12:58 2017 -0400

    glob: Do not assume glibc glob internals.
    
    It has been proposed that glibc glob start using gl_lstat,
    which the API allows it to do.  GNU 'make' should not get in
    the way of this.  See:
    https://sourceware.org/ml/libc-alpha/2017-09/msg00409.html
    
    * dir.c (local_lstat): New function, like local_stat.
    (dir_setup_glob): Use it to initialize gl_lstat too, as the API
    requires.
