binutils/:

	* configure.in: Don't define SKIP_ZEROES.
	* configure: Regenerate.
	* objdump.c (disassemble_data): Set skip_zeroes and
	skip_zeroes_at_end in disasm_info to defaults.
	(DEFAULT_SKIP_ZEROES): Rename from SKIP_ZEROES and always define.
	(DEFAULT_SKIP_ZEROES_AT_END): Rename from SKIP_ZEROES_AT_END and
	always define.
	(disassemble_bytes): Use skip_zeroes and skip_zeroes_at_end from
	objdump_disasm_info.

include/:
	* dis-asm.h (struct disassemble_info): Add skip_zeroes and
	skip_zeroes_at_end.

opcodes/:
	* disassemble.c (disassemble_init_for_target) <case
	bfd_arch_ia64>: Set skip_zeroes to 16.
	<case bfd_arch_tic4x>: Set skip_zeroes to 32.
