By adding those extra archives for jit targets like AMDGCN* then we bring in their transitive dependencies as well and then get the conflict with LLVM.so. This specific error had to do with libLLVMipo.a.

Does that mean that mean we don't need to link in these at all in dylib build? Could just guard the whole loop thing then.
