* conf/powerpc-ieee1275.rmk (grub_mkimage_SOURCES): Replace reference
	to util/powerpc/ieee1275/grub-mkimage.c with util/elf/grub-mkimage.c.

	* include/grub/types.h (#ifdef GRUB_CPU_WORDS_BIGENDIAN): Define
	grub_host_to_target16, grub_host_to_target32, grub_host_to_target64,
	grub_target_to_host16, grub_target_to_host32 and grub_target_to_host64.
	(#else): Likewise.

	* include/grub/powerpc/ieee1275/kernel.h (GRUB_IEEE1275_MOD_ALIGN):
	Renamed from to ...
	(GRUB_MOD_ALIGN): ...this.  Update all users.

	* util/elf/grub-mkimage.c: Replace grub_cpu_to_be16, grub_cpu_to_be32,
	grub_be_to_cpu16 and grub_be_to_cpu32 macros with grub_host_to_target16,
	grub_host_to_target32, grub_target_to_host16 and grub_target_to_host32,
	respectively.
