Based on patches from Eric Youngdale <eric@aib.com>:
* elflink.h (NAME(bfd_elf,size_dynamic_sections)): If -Bsymbolic,
output a DT_SYMBOLIC dynamic entry.
(elf_adjust_dynamic_symbol): If -Bsymbolic, don't require a PLT
entry for a locally defined symbol.
* elf32-i386.c (elf_i386_relocate_section): If -Bsymbolic, do warn
about undefined symbols, and fill in the GOT entry for a symbol
defined in a regular object file.
(elf_i386_finish_dynamic_symbol): If -Bsymbolic, output a RELATIVE
reloc rather than a GLOB_DAT reloc for a symbol defined in a
regular object file.
* elf32-m68k.c (elf_m68k_relocate_section): If -Bsymbolic, do warn
about undefined symbols, and fill in the GOT entry for a symbol
defined in a regular object file.
(elf_m68k_finish_dynamic_symbol): If -Bsymbolic, output a RELATIVE
reloc rather than a GLOB_DAT reloc for a symbol defined in a
regular object file.
* elf32-sparc.c (elf32_sparc_relocate_section): If -Bsymbolic, do
warn about undefined symbols, and fill in the GOT entry for a
symbol defined in a regular object file.
(elf32_sparc_finish_dynamic_symbol): If -Bsymbolic, output a
RELATIVE reloc rather than a GLOB_DAT reloc for a symbol defined
in a regular object file.
