Not only does it work pretty well, it also tries to do "the right
thing".  In a previous message, I tried to describe two distinct ld
modes: dumb mode and smart mode.  Dumb mode would just do what is
specified on the command line.  By contrast, smart mode could do
something more about shared library dependencies based on how symbols
are resolved.

Now, a smart mode, what could that be?  It's about either extra
dependencies which are unused (--as-needed), or missing/implicit
dependencies which can be obtained automatically (--copy-dt-needed-entries).
So, if there's anything like a smart mode, these two options togehter
are pretty smart.
