* elf32-i386.c: Don't defined ELF_ARCH etc. if this file is included by a target variant implementation. * elf64-alpha.c: Likewise. * elf32-i386-fbsd.c: New file. * elf64-alpha-fbsd.c: New file. * targets.c: Support bfd_elf32_i386_freebsd_vec and bfd_elf64_alpha_freebsd_vec. * configure.in: Accept the vectors bfd_elf32_i386_freebsd_vec, bfd_elf64_alpha_freebsd_vec. * Makefile.am (BFD32_BACKENDS): Add elf32-i386-fbsd.lo. (BFD32_BACKENDS_CFILES): Add elf32-i386-fbsd.c. (BFD64_BACKENDS): Add elf64-alpha-fbsd.lo. (BFD64_BACKENDS_CFILES): Add elf64-alpha-fbsd.c. (elf32-i386-fbsd.lo, elf64-alpha-fbsd.lo): Add dependencies. * config.bfd: For FreeBSD targets, set targ_defvec to a FreeBSD specific targets. Define OLD_FREEBSD_ABI_LABEL if appropriate. * config/tc-i386.h (ELF_TARGET_FORMAT): New macro. (TARGET_FORMAT): Use ELF_TARGET_FORMAT instead of "elf32-i386". * config/tc-i386.c (i386_target_format): Likewise. * config/tc-alpha.h (ELF_TARGET_FORMAT): New macro. (TARGET_FORMAT): Use ELF_TARGET_FORMAT instead of "elf64-alpha". * emulparams/elf_i386_fbsd.sh: Set OUTPUT_FORMAT to elf32-i386-freebsd. * emulparams/elf64alpha_fbsd.sh: Set OUTPUT_FORMAT to elf64-alpha-freebsd.
