support -Ur in the linker. * linker.c (generic_link_add_symbol_list): Remove bitsize argument from call to _bfd_generic_link_add_one_symbol. (_bfd_generic_link_add_one_symbol): Remove bitsize argument. Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR instead of bitsize to add_to_set call back. (_bfd_generic_final_link): Account for link_order relocs when allocating space for relocations. Handle them in link_order loop. (_bfd_generic_reloc_link_order): New function. (_bfd_default_link_order): If a reloc_link_order is seen here, abort. (_bfd_count_link_order_relocs): New function. * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize argument from declaration. (_bfd_generic_reloc_link_order): Declare. (_bfd_count_link_order_relocs): Declare. * libbfd.h: Rebuilt. * aoutx.h (aout_link_add_symbols): Remove bitsize argument from call to _bfd_generic_link_add_one_symbol. (NAME(aout,final_link)): Account for link_order relocs when allocating space for relocations. Handle them after handling all input BFDs. (aout_link_reloc_link_order): New function. * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from call to _bfd_generic_link_add_one_symbol. (ecoff_bfd_final_link): Account for link_order relocs when allocating space for relocations. Handle them in link_order loop. (ecoff_link_write_external): Set the storage class of a defined linker created symbol based on the section it is in. Correct bfd_link_hash_weak case to use .sc rather than .st. (ecoff_reloc_link_order): New function. * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle BFD_RELOC_CTOR. * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
