Also, made LIST properly handle full 64-chars lines not ending with
a null or CR. Previously, such a line would be accompanied by its
following line, duplicating that line's output.

boot: apply BIN( to stray stable ABI references
...
With cross compiling and IMMEDIATE words, things get icky with stable
ABI references. For the same reason that EXIT, (br) and (br?) need to
stay at stable offsets, these word references will not have BIN(
properly applied at Inner core xcomp.
The solution for now is to adjust during EXECUTE, which is ugly and
inefficient, but I don't see a better solution right now.
