* kern/powerpc/ieee1275/cmain.c (grub_ieee1275_find_options):
	Fix signedness warnings.
	* kern/powerpc/ieee1275/openfw.c (grub_available_iterate):
	Likewise.
	* util/ieee1275/get_disk_name.c: Include config.h so that
	_GNU_SOURCE is defined and getline() is declared.  Mark an
	unused argument as such.  Fix a signedness warning.
