ELF final_write_processing
Move setting of OSABI to final_write_processing, after symbols are written. This allows OSABI to be set based on symbols actually written to the output rather than assuming input symbols will be output. Corrects object files such as the one generated on powerpc64le-linux by ld-powerpc/pr23927.s which has a local STT_GNU_IFUNC symbol but prior to this patch the file was marked ELFOSABI_NONE. * elf-bfd.h (enum elf_gnu_osabi): Rename from elf_gnu_symbols. Remove none, any, all enums. (struct elf_obj_tdata): Rename has_gnu_symbols field to has_gnu_osabi. (_bfd_elf_final_write_processing): Declare. * elf.c (_bfd_elf_write_object_contents): Unconditionally call elf_backend_final_write_processing. (_bfd_elf_post_process_headers): Move body of function to.. (_bfd_elf_final_write_processing): ..here, but set EI_OSABI byte only when not already set. Adjust for rename. * elfxx-target.h (elf_backend_final_write_processing): Default to _bfd_elf_final_write_processing. * elf-hppa.h (elf_hppa_final_write_processing): Call _bfd_elf_final_write_processing. * elf-m10300.c (_bfd_mn10300_elf_final_write_processing): Likewise. * elf-nacl.c (nacl_final_write_processing): Likewise. * elf-vxworks.c (elf_vxworks_final_write_processing): Likewise. * elf32-arc.c (arc_elf_final_write_processing): Likewise. * elf32-avr.c (bfd_elf_avr_final_write_processing): Likewise. * elf32-bfin.c (elf32_bfin_final_write_processing): Likewise. * elf32-cr16.c (_bfd_cr16_elf_final_write_processing): Likewise. * elf32-cris.c (cris_elf_final_write_processing): Likewise. * elf32-h8300.c (elf32_h8_final_write_processing): Likewise. * elf32-lm32.c (lm32_elf_final_write_processing): Likewise. * elf32-m32r.c (m32r_elf_final_write_processing): Likewise. * elf32-m68k.c (elf_m68k_final_write_processing): Likewise. * elf32-msp430.c (bfd_elf_msp430_final_write_processing): Likewise. * elf32-nds32.c (nds32_elf_final_write_processing): Likewise. * elf32-or1k.c (or1k_elf_final_write_processing): Likewise. * elf32-pj.c (pj_elf_final_write_processing): Likewise. * elf32-v850.c (v850_elf_final_write_processing): Likewise. * elf32-xc16x.c (elf32_xc16x_final_write_processing): Likewise. * elf32-xtensa.c (elf_xtensa_final_write_processing): Likewise. * elf64-ia64-vms.c (elf64_vms_final_write_processing): Likewise. * elfnn-ia64.c (elfNN_ia64_final_write_processing): Likewise. * elf32-arm.c (arm_final_write_processing): Split out from..
