Well, the trouble was that configure believed it was a 32 bit system,
so I don't see much we can do there aside from attempting to compile
things in 64 bit mode.

Wouldn't it be better to create a SSE4.1a directory and use that
assembly code when SSE 4.1a is available? That seems to be the
prevailing way to do things.
On second though: according to http://en.wikipedia.org/wiki/SSE4 it
seems that there are three SSE4 flavors:
* SSE 4.1
* SSE 4.2
* SSE 4.1a
The last one seems to be K10 specific for now, but I would still
recommend to test for SSE 4.1a if your code is that specific.
