All linkers I know (even the MS ones) work that way, and (AFAICT)
always did.

It's the *only* reasonable way for linker to work.
If it didn't work that way, every program (when linked statically)
would include the *entire* code for all libraries it was linked
against (including libc, which is quite large).

You do have other solutions, e.g. explicitly list objects that must
be linked in, and the linker will do the right thing (pulling in
only necessary parts of the libraries).
