Well... not the cleanest solution, but since the core of the tests is
not affected by this workaround, OK for mainline and 4.3.

Hi,
Those AVX tests just include ssse3-*.c. They also need -fno-strict-aliasing.
I am checking in this patch into trunk and 4.4 branch.
Thanks.

SSSE3 tests are testing SSSE3 intrinsics. This patch adds
-fno-strict-aliasing to avoid posible aliasing problem without
affecting tests for SSSE3 intrinsic implementation. Tested on
Linux/Intel64. OK to install?
