* configure.ac: Accept `powerpc64' as host_cpu.
	(amd64): Rename to `biarch32'.

	* kern/powerpc/cache.S (grub_arch_sync_caches): Handle
	non-cacheline-aligned addresses.

	* kern/dl.c (grub_dl_load_core): Add grub_dprintf messages.
	(grub_dl_flush_cache): Likewise.  Only call `grub_arch_sync_caches'
	if `size' is non-zero.
