I'll add jvm, clr, and llvm to the list.  Such a list is inevitably
open-ended anyhow.

I'm not even sure why I left them out, though they belong on a different
list.  The JVM and CLR make it impossible to determine (short of native
code) what the underlying byte order is, however, so some systems will
have neither.

That's what I had in mind.
