Thank you for being willing to make that change.
I have no more principled objections; however, the code could be much
simpler. Now that it's opt-in, there's no reason to entangle it with
the x86 tuning code; it should be wholly controlled by the environment
variable. Also, why are you open-coding a loop over the contents of
__environ? Isn't this what __secure_getenv is for?
