I was misled by the configure portion, where the backfall to nasm was
made in case of X86, and I didn't realize the as_check "pabsw xmm0,
xmm0" would turn out good for my X86_64... well, it didn't with the old
version I had running, so I saw the error message following it.

Now everything is fine again, x264 is fast again (and even faster than
before, now I get ~40fps where I got ~30-35fps the first time around.
