In lieu of having multiple similiar lines, we can just have one
generic cpu-as line for CONFIG_ALTIVEC

---
Was hoping to get comments about this change and if anyone sees any potential
problems?

I have a memory that we can get some altivec instructions even with
CONFIG_ALTIVEC = n, though presumably they never get executed.  We
would have to check that before applying your patch.

How would we check that?
