GCC expects __stack_chk_fail() to be noreturn[1].  Returning from
__stack_chk_fail() can thus lead to subtle failures.

When crashing, use a volatile NULL pointer dereference.  Ideally we
would like to "abort()" here, but doing so would require two more
syscall definitions just for a cold function.  After all, the function
isn't even used at all if -fno-stack-protector is specified.

Also, don't say "stack smashing" (unlike glibc).  The preloader
currently initializes the stack canary value to a fixed value (0), which
serves little value in protecting against actual buffer overrun attacks.

Since most LDAP servers do not require mTLS, for now the callback
function is saved but not called.
