The combination of the 'abfd' pointer and the 'symbols' is probably unique.
But you are right - this cannot be guaranteed.

So the proper way to solve this problem is to create a new function, or
rather group of functions.  One to register a symbol table and then another
the perform scans using that symbol table.  And another function to free
any stored data, of course.

Then callers can choose which API to use.  Fortunately (or maybe
unfortunately) the BFD library has a history of having an unstable API,
so you do not have to worry about versioning.
