llvm dev - Feb 2019 - kaleidoscope ch4 jit example regression?

Hi Nick,

I was not aware of it, but it makes sense given the recent switch to ORC2, which
has different symbol resolution rules.

I am out on vacation this week, but will take a look when I get back and see if
I can restore the old behavior.

Cheers,
Lang.

Chapter 4 behaves as you describe, and not as the documentation shows. Looks
like somethnig needs updating (either source or the documentation).

Not yet unfortunately. I've had my head down working on a jut-linker
replacement.

Let me take a look right now...
