sh: Explicit endian selection support.
Previously big endian was simply assumed if little endian was not set, which led to some cflags ordering issues. There's not much point to not having a big endian option, so shove one in a choice and wire it up in the Makefile. This lets us clean up some of the cflags ordering while we're at it.
