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.

might need to adjust addr. Ugly, but well... )

Make BIN( offsetted binaries closer to working at all I have a working offset-by-0x100 stage0 now.
