Upon further review I think these additions to needed_by should be
dropped, or moved to a separate change if deemed correct. They alter
rpath processing. For ldso it doesn't matter since ldso has no deps,
but for LD_PRELOAD libs, the change causes them to use the main app's
rpath for finding their deps, which may or may not be reasonable, but
is a functional change unrelated to dependency-order ctor execution.
