You know, I think it's actually just endianness right now; I don't see
where word size comes into it, except for the cookie.

Anyway, in the future when we do AOT compilation, this question will be
more serious.  (I would like to do AOT stuff this year.)  So, following
the autoconf manual ("Specifying Target Triplets"), we would have build
== host, but target == the arm triple; so we would need
`target-endianness' (and possibly `target-word-size') in the compiler.

Where do you think we should put these, given that you don't want them
in (rnrs bytevectors)?  :-)
