* bfd/elf64-sparc.c: Add FreeBSD support.
(elf64_sparc_fbsd_post_process_headers): New function.
* bfd/targets.c (_bfd_target_vector): Add bfd_elf64_sparc_freebsd_vec.
* bfd/config.bfd (sparc64-*-freebsd*): Set targ_defvec to bfd_elf64_sparc_freebsd_vec.
* bfd/configure.in: Add entry for bfd_elf64_sparc_freebsd_vec.
* bfd/configure: Regenerate.
* gas/config/tc-sparc.c (md_parse_option): Treat any target starting with elf32-sparc
as a viable target for the -32 switch and any target starting with elf64-sparc as a
viable target for the -64 switch.
(sparc_target_format): For 64-bit ELF flavoured output use ELF_TARGET_FORMAT64
while for 32-bit ELF flavoured output use ELF_TARGET_FORMAT.
* gas/config/tc-sparc.h (ELF_TARGET_FORMAT, ELF_TARGET_FORMAT64): Define.
* ld/emulparams/elf64_sparc_fbsd.sh (OUTPUT_FORMAT): Define as elf64-sparc-freebsd.
