With cross compiling and IMMEDIATE words, things get icky with stable

stay at stable offsets, these word references will not have BIN(
properly applied at Inner core xcomp.

inefficient, but I don't see a better solution right now.

Stop LOADing on ABORT
...
This is done by adding a "C<* override" layer that is reset to 0 on
ABORT.
The problem was that when ABORT happened during a LOAD, we had a
resetted RSP and started from a clean INTERPRET, but LOAD didn't
have the opportunity to restore C<*, which caused it to continue
interpreting from the faulty BLK.
With a C<* override, we don't need to *restore* C<*, we just need to
clear the override.

Replace the "> " prompt with the more traditional "ok" one
...
This is more than cosmetic, it's also highly usable. The presence
or absence of the "ok" message allows us to know whether the command
aborted. Previously, the "> " prompt appeared when the system expected
a prompt in the INTERPRET context, whether the previous command aborted
or not.
Also, this allows us to get rid of that ugly FLAGS global variable.
