Fixed bug 3993 - altivec.h include in SDL_cpuinfo.h breaks compilation with -std=c++11

bastien.bouclet

According to this GCC bug report, altivec.h requires building with the gnu extensions: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78263.

As an application developer, I don't want SDL to force me to enable the gnu extensions.
