+From 193f1e81edd6b1b56b0eb0ff8aa4b41c7b4257b4 Mon Sep 17 00:00:00 2001

+Subject: 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.
