Subject: 	* elfxx-mips.c (_bfd_mips_elf_discard_info): New function,
 code from 	elf32-mips.c. 	(_bfd_mips_elf_write_section): Likewise. 
 * elfxx-mips.h (_bfd_mips_elf_discard_info): New prototype. 
 (_bfd_mips_elf_write_section): Likewise. 	* elf32-mips.c
 (elf32_mips_discard_info): Move to elfxx-mips.c. 
 (elf32_mips_write_section): Likewise. 	* elf64-mips.c
 (_bfd_mips_elf_ignore_discarded_relocs): Use it. 
 (_bfd_mips_elf_write_section): Likewise.
