Nope.  They have AES on the die, but its not the AES-NI that's the
topic here.  AES-NI was added in 2010 in the Core-i5/i7 families and
in 2012 in the AMD A10 cores.

That's how this thread started.  Full AES-NI support is in the default
compiler (clang) in the base system for amd64 and i386 but there's
missing pieces with the old built-in gcc+binutils.  If you BYO newer
version of gcc+binutils, that would work too.
