Fixed by using GCC 4.9.2 instead of 4.8.4.

glad you found it!

Good morning,
I actually have the same problem on an openSUSE Leap 42.1 x86_64 machine (gcc 4.8.5) with an Core2Duo based Xeon since atlas 3.11.36 (didn't check 35). Changing the compiler is no option.
I'm not quite sure about the logic, but cat /proc/cpuinfo shows SSSE3, but not SSE3 (not sure, whether it is always like that). Changing the compile flag -msse3 to -mssse3 manually after the configure makes the atlas compile just fine.

Best Robert
