Right -- utime(2) [and therefore touch(1)] doesn't work on symlinks.  Here
is a solution: delete and recreate all the bad links. 

The following program will do the job for one file, and you can invoke
it thusly (assuming it's called fixlinkdate):
	% find / -type l -exec fixlinkdate {} \;

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <time.h>
#include <sys/types.h>
#include <sys/stat.h>

int main(int argc, char **argv)
{
	int i, y;
	char filename[1024];
	struct stat link;
	struct tm *t;

	if (argc != 2) {
		fprintf(stderr, "usage: %s filename\n", argv[0]);
		exit(-1);
	}

	/* Get the link's target and other details. */

	if ((i = readlink(argv[1], filename, 1023)) < 0) {
		fprintf(stderr, "%s is not a valid symbolic link\n", argv[1]);
		exit(-1);
	}
	filename[i] = 0;

	if (lstat(argv[1], &link) < 0) {
		perror("lstat");
		exit(-1);
	}

	/* Sanity check. */

	t = localtime(&link.st_mtime);
	y = t->tm_year + 1900;
	if (y != 2018) {
		printf("year on %s is %d\n", argv[1], y);
		exit(1);
	}

	/* Delete the symbolic link and recreate it. */

	if (unlink(argv[1]) < 0) {
		perror("unlink");
		exit(-1);
	}
	if (symlink(filename, argv[1]) < 0) {
		perror("symlink");
		exit(-1);
	}

	/* Set the owner back. */

	chown(argv[1], link.st_uid, link.st_gid);
}

Note that this program only recreates links that have a year of 2018,
which was the case for my system also.  You can obviously change that
value to anything.
