Is there filter-like functionality in binutils?

An ELF filter is a shared object that can "filter" another object (the
filtee).  It's mostly useful for three purposes: providing stubs for
symbols whose implementations have moved from one object to another,
providing stubs for possibly-not-installed functionality, and
interposition on specific objects/symbols (and without having to use
LD_PRELOAD).

Is there any such functionality in binutils/gold/rtld?
