That is a known problem with every RISC architecture supporting
no-threading: I have not yet implemented far jumps, so any jump whose
displacement does not fit in one instruction as an immediate will fail
like that.

I have temporarily disabled no-threading on RISC-V as well, which will
work around this issue for the time being.

I want to implement a real solution, of course, but for that I would
like to rewrite the file (quite horrible) jitter-replicate.c .  This
will work for the time being.
