-maltivec allows acces to the Altivec ABI. But gcc cannot perform
auto-vectorization on its own (yet). So compiling -maltivec won't change
anything if the code does not contain Altivec instructions (in the form
of assembly instructions or their C versions). And in that case, it
would not even compile without -maltivec :)
