In general you want to look at the OpenBSD support instead of NetBSD.  It's in a much better shape ;).

You'll need to add something like:

  gdbarch_register_osabi (bfd_arch_rs6000, 0, GDB_OSABI_FREEBSD_ELF,
                          ppcfbsd_init_abi);
  gdbarch_register_osabi (bfd_arch_powerpc, 0, GDB_OSABI_FREEBSD_ELF,
                          ppcfbsd_init_abi);

(both lines seem to be necessary given the way BFD makes a distinction
between rs6000 and powerpc, but ELF doesn't).
