Brecht Van Lommel e9d03296c7 Better fix for #36935 and 36316:
* 32 bit GCC builds now have the SSE BVH optimizations turned off, but still
  compile with SSE flags for better performance.

* White color when rendering on Windows seems to have been unrelated to SSE,
  rather it was a graphics driver not supporting half float textures, added a
  check for that now.
