This has been attached to bug 25663 for a bit now, but didn't get
reviewed here. It seems like a smarter way to go about setting up
the CPU_TO_LE32 macro, because it should do a correct but potentially
suboptimal thing on platforms we don't know about (instead of breaking
the build).

Subject: [PATCH] mesa: Fallback on C byteswap.
Only attempt using a platform-specific byteswap routine on
platforms where we know it will work.
