* include/grub/dl.h (grub_dl_check_header): New prototype.
	(grub_arch_dl_check_header): Change return type to grub_err_t,
	remove size parameter and export function.  Update all callers.
	* kern/dl.c (grub_dl_check_header): New function.
	(grub_dl_load_core): Use `grub_dl_check_header' instead of
	`grub_arch_dl_check_header'.  Check ELF type.  Check if sections
	are inside the core.
	* kern/i386/dl.c (grub_arch_dl_check_header): Remove arch
	independent ELF header checks.
	* kern/powerpc/dl.c (grub_arch_dl_check_header): Likewise.
	* loader/i386/pc/multiboot.c (grub_rescue_cmd_multiboot): Use
	`grub_dl_check_header' instead of explicit checks.  Check for the
	ELF type.
	* loader/powerpc/ieee1275/linux.c (grub_rescue_cmd_linux): Use
	`grub_dl_check_header' instead of explicit checks.  Remove arch
	specific ELF header checks.
