based on sections stored in xcoff_data.
* coff-rs6000.c (xcoff_copy_private_bfd_data): Copy new xcoff_data
fields.
(xcoff_reloc_type_lookup): Handle BFD_RELOC_CTOR.
(rs6000coff_vec): Set symbol_leading_char to '.'.
* coffgen.c (coff_get_symbol_info): If fix_value is set, fix the
value stored in ret rather than returning a pointer value.
