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.
