Details:

According to the manual the wildcard function "is replaced by a
space-separated list of names of existing files ...". However, it does not
find a symbolic link which exists but does not point to an existing file
(apparently wildcard uses stat, not lstat). It's not clear to me whether this
is a code or a documentation bug but it ought to be clarified in the doc at
the least. Here's a test case:

% ls -lrt
total 4
-rw-rw-r-- 1 xxxxxxx users 42 Oct 10 06:24 Makefile
lrwxrwxrwx 1 xxxxxxx users 11 Oct 10 06:24 yes -> /etc/passwd
lrwxrwxrwx 1 xxxxxxx users  9 Oct 10 06:25 no -> /etc/asdf

% cat Makefile
$(info FOUND: $(wildcard yes no))
all:;@:

% make
FOUND: yes
