Apple Inc version cctools-782~33, GNU assembler version 1.38

Under xcode 4, on clang support AVX. Because of the GPL3 license, Apple will no longer support gcc version newer than 4.2.1. Must be some legal issues that Apple does not like in GPL3.

OpenMP works as well. I had to add -static-intel to compile flags so it would run without needing access to libiomp5.dylib.
