Sounds like your tool chain doesn't have the necessary support for
AES-NI...  Are you using gcc as cc?  If so, do you have the necessary
tool chain work that I did in r255185 in your local tree?

Can you compile this test program?

------ tsse.c start ----
#include <wmmintrin.h>

__m128i foo;
------  tsse.c end ------

With the command:
${XCC} -c -maes tsse.c

If you can't, then the problem is your toolchain, and you need to fix
it...  Try also w/:
clang -c -maes tsse.c

and it's also helpful to know more info, like: ${XCC} --version

Thanks.
