This matches the gold and bfd behaviour?

I would actually expect the .so to keep bar2 alive.  After all, if a symbol in a .so can force us to export a symbol from an executable, why shouldn't it for us to keep it alive?

That is similar to us not gcing section that contribute to the dynamic table of a .so.
