One of the parameters to the magical "register a thread-local destructor" function is called `__dso_handle` and largely just passed along (this seems to be what other implementations do). Currently we pass the *value* of this symbol, but apparently the correct piece of information to pass is the *address* of the symbol. In a PIE binary the symbol actually contains an address to itself which is why we've gotten away with what we're doing as long as we have. In a non-PIE binary the symbol contains the address `NULL`, causing a segfault in the runtime library if it keeps going. Closes #24445
