Re: 64 bit F7

Since requirements for computers are more intense now, building 32-bit
with SSE/SSE2 by default would make sense, especially if a 20%
improvement is noticed in comparison.
Note that not all 32 bit processors have the SSE/SSE2 extensions - This
is why gcc does not enable this by default in 32 bit mode. All 64 bit
processes do so gcc can safely enable it by default, knowing that its
not going to generate code that some processors cannot run.
