zld: throw an error if found unknown section in object

We will silently ignore expected section that are either won't take
part in linking such as any `__DWARF` section, or are known but are
not yet implemented such as `__TEXT,__eh_frame`. For any other
we will throw an error and exit.

Also, inform the caller that we currently are unable to handle
frameworks.
