That's the headers, I don't see anything wrong.  The sections are
missing, but it has always been like that.  The version is current from
CVS.

$ ./grub-mkimage -o grub.img -d . *.mod
$ objdump -x grub.img

grub.img:     file format elf32-powerpc
grub.img
architecture: powerpc:common, flags 0x00000102:
EXEC_P, D_PAGED
start address 0x00010000

Program Header:
    LOAD off    0x000000c0 vaddr 0x00010000 paddr 0x00010000 align 2**4
         filesz 0x0000bf04 memsz 0x000133a8 flags rwx
    LOAD off    0x0000bfc4 vaddr 0x100000b4 paddr 0x100000b4 align 2**2

         filesz 0x00052104 memsz 0x00052104 flags rwx

Sections:
Idx Name          Size      VMA       LMA       File off  Algn
SYMBOL TABLE:
no symbols


The image loads, complains about "cursor-on", shows "Welcome to GRUB"
and the prompt.  "lsmod" shows an empty list.
