Richard are you sure we can break O_NOFOLLOW and still expect the machine to
boot?

./elf/cache.c:  fd = open (temp_name, O_CREAT|O_WRONLY|O_TRUNC|O_NOFOLLOW,
./elf/dl-profile.c:#ifdef O_NOFOLLOW
./elf/dl-profile.c:# define EXTRA_FLAGS | O_NOFOLLOW

./elf/rtld.c:      const int flags = O_WRONLY | O_APPEND | O_CREAT | O_NOFOLLOW;
./include/asm/fcntl.h:#define O_NOFOLLOW        0400000 /* don't follow links */
./sysdeps/generic/check_fds.c:     the O_NOFOLLOW flag for open() but only on some system.  */
