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.
