This type of logic doesn't belong in lib/Linker. The code in
lib/Linker is the most central part of IR linking. The only logic in
there should be the one that is needed by all liking paths. That is
not the case for any solution using a native linker, since the
semantic of all such linkers is to load an entire object file at a

Which also brings the question, why do this instead of using an
archive? An archive with multiple IR files would let you use the same
logic native linkers use and be more efficient.
