SSE & clang 3.7

[Riccardo Mottola]

Hi!

I am trying quite stubbornly to compile ArcticFox on 10.5.

When using clang 3.9, which I know works fine on 10.6 and produces 
good results, I get an "illegal instruction" at a certain point and 
"don't know from what". I have issues using gcc 6.5 on Mac (works on 
other platforms.
Clang 3.4 has the same issue.

I wanted to try 3.7, but I get this error.

it is inside clang, I suppose either a bad build of 3.7 or a missing 
flag? Do you have any suggestions/ideas???
Since clang 3.4 and 3.9 do not have thi, I suppose it is a 3.7 error.
