So how can it be fixed?

Not sure.  As I said, it's not easy.  As far as I understand things,
INTERNALIZE_SYMBOL() should look at n_type to decide whether n_value
should be treated as a signed or an unsigned value.  The problem seems
to be that n_value can either be interpreted as an address or as an
offset.  Addresses should be sign-extended based on what
bfd_get_sign_extend_vma() tells us.  Offsets should probably always be
sign-extended.

How about sign extending it a bit alter in process_one_symbol when we find out it's a stack variable? I cannot imagine an architecture where a stack variable has an absolute address. But my imagination is limited.
