It would be cool to grab the sse2 versions, too.

Even the sse2 version is significantly faster than the compiled version.

There is still a large deployment of systems which lack ssse3 or avx

Plus, most of the (affordable) KVM-based virtual offerrings run qemu-kvm
with options which block everything newer than sse2, even when the host
cpu supports them.  (One hopes that those vendors will upgrade to qemu 2
and start using -cpu host, but one cannot hold one's breath that long.)
