This adds ABI flags to MIPS/ELF object files.
For bfd:
* elf32-mips.c (elf_mips_abi_name): New.
(_bfd_mips_elf_merge_private_bfd_data): Compare EF_MIPS_ABI flags.
For gas:
* config/tc-mips.c (mips_abi_string): New.
(md_parse_option,md_longopts): Add mabi.
(mips_elf_final_processing): Set e_flags based on mabi flag.
For gcc:
* config/mips/mips.h (GAS_ASM_SPEC): Pass mabi to gas.
(ABI_GAS_ASM_SPEC,abi_gas_asm_spec): New.
(EXTRA_SPECS): Added ABI_GAS_ASM_SPEC,abi_gas_asm_spec.
For include/elf:
* mips.h (EF_MIPS_ABI,E_MIPS_ABI_O32,E_MIPS_ABI_O64,
E_MIPS_ABI_EABI32,E_MIPS_ABI_EABI64):
