Questions about LTO infrastructure and pragma omp target

Unfortunately, I missed the Cauldron, though I'm familiar with the
general idea and now I'm trying to clarify details.

Oh, if we just link the target binary as a data section into the host
binary, then I see no problems in that, it seems absolutely feasible
with the existing infrastructure.  I just thought (seemingly it was
incorrect) that we're speaking about linking of target code with the
host code.

Thanks, I'm sure in that too:)
