indirection.
(elf_link_add_object_symbols): If the real name of the symbol gets
overridden, convert the versioned symbol into an indirect symbol
to the real symbol.
* elf32-ppc.c (ppc_elf_relocate_section): Don't emit R_PPC_REL*
relocs in shared libraries which refer to local symbols. Cope
with addend when processing a GOT relocation.
* elf32-ppc.c (ppc_elf_size_dynamic_sections): Only create symbols
for sections that the linker didn't create.
(ppc_elf_finish_dynamic_sections): Only try to write out a section
symbol if it was created in ppc_elf_size_dynamic_sections.
(ppc_elf_relocate_section): Complain if we have to generate a reloc
relative to a section for which we didn't output a symbol.
* elf32-ppc.c (ppc_elf_size_dynamic_sections): Clean up. PLT
relocs are 'rela' relocs, like everything else. .rela.plt is not
a read-only section, so we don't have to special-case it.

.rela.bss section are (of course) 'rela' relocs not 'rel' relocs.

characters, not 4.
* elf32-ppc.c (ppc_elf_check_relocs): Use
_bfd_elf_create_got_section to create the GOT rather than
ppc_elf_create_linker_section. Create the '.rela.got' section
ourselves.

(ppc_elf_create_linker_section): Delete unused LINKER_SECTION_GOT
stuff.
* elf32-ppc.c (ppc_elf_howto_raw): GOT16_HA relocs should be
treated in a similar way to ADDR16_HA relocs.
(ppc_elf_relocate_section): PLTREL24 relocs do not get copied into
shared objects; the linker must deal with them.
(ppc_elf_create_linker_section): Stop setting
_GLOBAL_OFFSET_TABLE_ to the wrong value; delete unused
LINKER_SECTION_PLT stuff.
(ppc_elf_check_relocs): Delete unused LINKER_SECTION_PLT stuff.

section, not ELF-specific calls.

(elfNN_bed): Set added fields.
* elf32-ppc.c (ppc_elf_size_dynamic_sections): Was setting
DT_RELENT in shared objects; should be DT_RELAENT.
* elf32-ppc.c (ppc_elf_relocate_section): Propagate
R_PPC_ADDR16_HA relocs to shared objects. Cope with case where
such a reloc (in a non-shared object) refers to a symbol that's
not defined.
* elfcode.h (put_signed_word): Define.
(get_signed_word): Define.
(elf_swap_reloca_in): Use get_signed_word for the r_addend field.
(elf_swap_reloca_out): Use put_signed_word for the r_addend
field.
* elf32-m68k.c (elf_m68k_finish_dynamic_symbol): Use
bfd_get_signed_32 to set the r_addend field.
* elf64-mips.c (mips_elf64_swap_reloca_in): Use
bfd_h_get_signed_64 to set the r_addend field.

elf_adjust_dynamic_symbol.
(elf_adjust_dynamic_symbol): Call elf_fix_symbol_flags.

forced local even if NEEDS_PLT is set. When forcing a symbol to
be local, clear NEEDS_PLT.
(elf_link_output_extsym): Remove unused local bed.
for a symbol which is being forced to be local.
* elf32-i386.c (elf_i386_relocate_section): Write out the
relocation value for a GOT reloc for a symbol which is turning
into a local symbol.
(elf_i386_finish_dynamic_symbol): If a symbol is turning into a
local symbol, write out a RELATIVE reloc rather than a GLOB_DAT
reloc.
* elf32-m68k.c, elf32-sparc.c: Corresponding changes.

global variables to static.
(_bfd_coff_write_task_globals): New function.

rather than TIC80.
