* configure.ac: Check for TARGET_CFLAGS initialization before we
	initialize it ourselves (sigh).
	Move a few modifications to TARGET_CFLAGS to be unconditional
	(extra warning flags, loop alignment, i386 CPU extensions, GCC 4.4
	eh_frame)
	
	* gettext/gettext.c (grub_gettext_delete_list): Add `void' argument.
	* term/i386/pc/at_keyboard.c
	(keyboard_controller_wait_untill_ready): Likewise.
	(keyboard_controller_led): Rename `led_status' paramter to avoid
	name conflict.
