* include/grub/ieee1275/ieee1275.h (grub_ieee1275_flag): Add
	GRUB_IEEE1275_FLAG_BROKEN_OUTPUT flag.
	* kern/powerpc/ieee1275/cmain.c (grub_ieee1275_find_options): Set this
	flag when running on SmartFirmware.
	* term/ieee1275/ofconsole.c (grub_ofconsole_init): Avoid running
	"output-device output" command when GRUB_IEEE1275_FLAG_BROKEN_OUTPUT
	was set.

	* kern/powerpc/ieee1275/openfw.c (grub_ieee1275_encode_devname):
	Increase partno when GRUB_IEEE1275_FLAG_0_BASED_PARTITIONS flag is set,
	rather than decreasing it.

	* util/i386/pc/grub-setup.c (setup): When embedding is required, but
	there's not enough space to do it, fail in the same way as when it
	can't be done because there are no partitions.

	* util/powerpc/ieee1275/grub-install.in: Improve error message shown
	when nvsetenv failed.
