FWIW, that got caught by sparse, but I would really recommend _testing_
on big-endian - getting an emulated headless e.g. mips box is fairly
easy with qemu; I'd done that with debian big-endian mips userland on
emulated malta and it didn't take much work to set up.

Speaking of sparse, I think we simply ought to add -D__CHECK_ENDIAN__
to CHECKFLAGS in top-level Makefile. It's not _that_ much noise
these days... Not sure which tree should that go through, though...
