this is enabled by default on amd64

Can you elaborate a bit here?
When I builded in clean chroot (amd64) I never noticed that these flags would be added.

It is done by default by the compiler internally.

Aha ... so these default flags are added by compiler and they are not controlled by debian tools at all?

Can I see somewhere default flags for different archs?
