I'm not really familiar with sparc machines... does that values sound good to
you?  Does it seem to match the machine you have?

In any case, that seems to match the osabi registration line in sparc64-fbsd-tdep.c:

  gdbarch_register_osabi (bfd_arch_sparc, bfd_mach_sparc_v9,
			  GDB_OSABI_FREEBSD, sparc64fbsd_init_abi);

Is the file sparc64-fbsd-tdep.c being compiled?  In other words, does the
file gdb/sparc64-fbsd-tdep.o exist in your build directory?
