Tidy ups to get GDB to compile

bfd:
	* elf32-avr32.c (avr32_size_frags, avr32_elf_relocate_section)
	(avr32_elf_relocate_section): Comment out unused variables.
	(avr32_elf_grok_prstatus, avr32_elf_grok_psinfo): Replace
	core_signal, core_pid, core_program and core_command by
	corresponding members of core struct.
	* po/bfd.pot: Regenerated.

gas:
	* configure: Regenerated.
	* configure.tgt: Add avr32.

gdb:
        * avr32-tdep.c (avr32_register_type): Return correct types.
        (avr32_register_name): Add gdbarch parameter.
        (avr32_set_sysreg_command): Use gdb_byte as buffer type, and
	endian parameter when storing.
        (avr32_show_sysreg_command): Use gdb_byte as buffer type, and
	endian parameter when extracting.
        (avr32_breakpoint_from_pc): Add gdbarch parameter.
        (gdb_print_insn_avr32): use target_gdbarch to get current arch.
        (avr32_return_value): Add function to arg list, make buffers gdb_byte.
        (avr32_analyze_prologue): Add gdbarch parameter, add endian
	parameter when reading memory.
        (avr32_skip_prologue): Add gdbarch parameter, use gdb_byte buffer.
        (avr32_frame_align): Use gdb_byte buffer.
        (avr32_unwind_sp, avr32_unwind_pc): Use gdb_byte buffer and add
	endian paremter when extracting value.
        (avr32_dummy_id): Renamed from avr32_unwind_dummy_id and
	restructure to use THIS frame.
        (avr32_frame_cache): Get gdbarch from frame.
        (avr32_frame_prev_register): Updated prototype, and modified
	contents accordingly
        (avr32_frame_base_address): Created.
	(struct avr32_frame_unwind): Rewritten with designated initializers.
        (avr32_frame_base_sniffer): New, replaces avr32_frame_sniffer.
        (avr32_gdbarch_init): Replace set_gdbarch_unwind_dummy_id with
	set_gdbarch_dummy_id, use frame base rather than frame unwind sniffers.
        (_initialize_avr32_tdep): Added extern declaration.
        * gnulib/aclocal.m4: Regenerated.
        * gnulib/configure: Regenerated.
        * remote.c (remote_xfer_partial): Add support for
	TARGET_OBJECT_SYSREG.
        * target.h (enum target_object): Add TARGET_OBJECT_SYSREG.

opcodes:
