Am I right in thinking that I should be looking in the file "bfd/linker.c",
Line 1382, at the function "_bfd_generic_link_add_one_symbol", which you
can see here:

    https://github.com/bminor/binutils-gdb/blob/
4a2318c9858fdb1899157339f526df3d20e43cfe/bfd/linker.c#L1382

So if the linker is looking through a load of object files (.o), static
archives (.a), and shared libraries (.so), every symbol encountered will be
processed by the "add_one_symbol" function.

And so if I add a few lines to that function to detect symbols beginning
with "_ZTI", I can add these symbols to a global container for all the
vtables. Also I can detect all the type_info's too.

Am I barking up the right tree?
