The copy in that directory can have any name you like. BFD will try
all. Note that
that is the copy that nm and ar will use. The linker (gold) requires you to pass
-plugin to it.

Looks like it found libLTO. Another case I have seen is when the
plugin is linked with a different libstdc++ than gold. Is that the
case? You do have libstdc++ in an unusual location...
