Not quite.

Your cpu is not 686; stop trying to pretend it is.

Now, maybe it is good idea to run libc6-686 on it. If you can
guarantee it contains no NOPL, fix whatever code is responsible for
selecting libc to use libc6-686 to use that. (Bonus points for
renaming libc6-686 to something more suitable. libc6-cmov?)
