(Get the code!)
According to the response here: https://<email address hidden>
...the call to xgetbv should be guarded against processors that don't support the instruction. The attached patch seems to work for me but must admit I am way out of my depth here (I understand nothing about cpu architecture, features, etc...) and have not tested on anything but my old MacBook Pro (15-inch, Mid 2010) / MacBookPro6,2. All that I can say is that for this machine the call to xgetbv is not made and everything seems to work. I have no idea if this is correct for other machines/processors or if it correctly detects support of this call...
