* lynx-nat.c (child_wait): Correct handling of byte reversed SPARC

	* lynx-nat.c (child_wait): Correct handling of byte reversed SPARC
        Lynx wait status.
	(fetch_core_registers): Don't try to fetch a register if
	regmap maps it to -1.
	* sparc-tdep.c (sparc_frame_find_saved_regs): Use FRAME_SAVED_I0
	and FRAME_SAVED_L0 when setting saved_regs_addr.  SPARC Lynx
	stores the registers in a weird order.
These patches make SPARC Lynx gdb usable, though it still has problems.
