Hi Surya,

SSE3 instructions are not enabled by default. 
To enable, you can either tell gcc your CPU architecture (-march=<arch>) as
suggested
by Marc, or enable just the specific SSE version that's supported by your
CPU (e.g.,
make TOOLCHAIN_CFLAGS="-msse4")

See http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html for a
list of CPU
architectures and instruction flags.

Regards,
Etai

Changing the CPU type emulation to some model that supports SSSE3 solved it
(e.g. core2duo) should do the trick. I faced the same problem sometime ago.
