icore: add BIN+
...
This allows us to write LATEST at proper offset in emul/stage1.fs in
cases where we set a nonzero BIN(.

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.

Will be useful as kinds of "#ifdef"s during xcomp.

Change C<? mechanic
...
It's now a simple flag updated by the C< implementation. No more
routine pointer.
The goal is to avoid tons of "ok" during a LOAD operation.

The SD card driver is a bit too slow to be bearable. I'll write
_crc16 in z80 and see how it goes.
