I believe that, for the purposes of the manual library probes, they will
amount to the same thing.

On ELF platforms with dynamic libraries, because the rest of the libraries
are pulled in by transitive library dependencies.

It would not (but is supposed to) work with static linkage or on platforms
where shared libraries cannot declare a dependency on other shared
libraries.  And if it did work there, I believe it would also work
properly in this particular case (albeit somewhat by accident).

I think that OpenAFS should separately probe for the actual libraries it
uses because I think that's more robust and more correct, but I believe
that fixing the manual library probing so that it would work properly for
static linkage is valuable and, as it so happens, would also fix OpenAFS's
immediate problem.
