I have not yet rebuilt llvm-3.4.2 to give shared libraries.
I tried to apply the patch (llvm-fix.patch) and looked that this fixed the 
issue.
Surely the patch enabled to set LEGACY_PASSMANAGER flag and octave build was 
done successfully.
In addition, I confirmed jit worked.

I strongly appreciate to the efforts by all people concerning the matter.

I will try shared llvm-3.4.2 build and tried to link to octave (default branch).
