* lib/fts.c (fts_stat): If lstat fails, report its errno, which
may be EOVERFLOW; this is likely more useful than reporting the
stat errno.
* lib/glob.c (link_stat): Rename from link_exists2_p and
return -1/0 instead of 0/1. Caller changed.
* lib/glob.c (link_exists_p):
* lib/renameat2.c (rename_noreplace, renameat2):
* lib/tempname.c (try_nocreate):
If errno == EOVERFLOW then the directory entry exists, so do not
act as if it does not exist.
