Subject: [PATCH] MIPS/BFD: Factor out ABI flag merging
Factor out the parts of `_bfd_mips_elf_merge_private_bfd_data'
responsible for ABI flag merging to `mips_elf_merge_obj_abiflags'. No
functional change.
bfd/
* elfxx-mips.c (mips_elf_merge_obj_abiflags): New function,
factored out from...
(_bfd_mips_elf_merge_private_bfd_data): ... here.
