Hmm, I think you're right. It's possible to override a library symbol
when you link an object, but symbol clashes in libraries should result
in hard errors.

No, I did.
In any case, it might be possible, even though extremely unlikely and
of very bad taste, that the symbols of liba that are pulled by libx
depend on libb. In this case, omitting the first occurrence of -la
would cause the symbols in libb to not be resolved.
