The big issue with properly supporting the PC-based lookups, and minsyms
in general, is that we don't actually have a properly set up BFD struct.
And, as far as I know, there's no way to actually create one without go-
ing through the trouble of generating an actual binary file in memory
and having the library read back from it.

So I did the best I could that wouldn't also have to involve potentially
fairly invasive changes to the rest of GDB.

Of course, I could be wrong and there might be a way to properly do what
I'm trying to do, but if there is one, I couldn't find it.

Yeah, that makes sense. I'll change it so that it uses gdb.Architecture.

Yes, I didn't realize the gdbpy_ref increased the refcount
automatically.

I don't have anything to add for the other points, so suffice to say
I'll fix everything you pointed out and submit a v3 as soon as I can.

Thanks for your time.
