> lp_build_fetch_rgba_soa fetches a texel from a texture.
> Part of that process involves first gathering the element
> together from memory into a packed format, and then breaking

> values.
> This commit attempts to correct the problem by reversing the order
> the packed values are read on big endian systems.
