* configure.ac: Define HAVE_LINUX_REGSETS even if PTRACE_GETREGS

	is not available.  Define HAVE_PTRACE_GETREGS if it is.
	* config.in, configure: Regenerated.
	* configure.srv: Set srv_linux_regsets for PowerPC and PowerPC64.
	* linux-i386-low.c, linux-m68k-low.c: Update to use
	HAVE_PTRACE_GETREGS.
	* linux-low.c (regsets_fetch_inferior_registers)
	(regsets_store_inferior_registers): Only return 0 if we processed
	GENERAL_REGS.
	* linux-ppc-low.c (ppc_fill_gregset, target_regsets): New.
	* linux-ppc64-low.c (ppc_fill_gregset, target_regsets): New.
