Change _bfd_elf_link_setup_gnu_properties to bfd *
Change setup_gnu_properties to return the first relocatable ELF input with GNU properties so that a backend can make decision based on GNU properties. * elf-bfd.h (elf_backend_data): Change setup_gnu_properties to return bfd *. (_bfd_elf_link_setup_gnu_properties): Return bfd *. * elf-properties.c (_bfd_elf_link_setup_gnu_properties): Return the first relocatable ELF input with GNU properties.
