I just check your qemu program, using
GNU binutils version 2.14.90.0.8 20040114
in a 32 bits x86 environment and
GNU binutils version 2.15.90.0.1.1 20040303
in a amd64 environment on Gentoo.
The two versions show me the same problems:
- ELF flags say the executable has symbols, but objdump isn't able to
find them.
- the .opcodes section (which should contain the PPC opcodes tables)
pretend 8 bytes aligned but is, in fact, 16 bytes aligned.
- this section is quite empty: only 20 bytes, when it's 4992 bytes long
in my version.
- I failed to find the opcode tables in any section.

it seems that the binary has been partialy stripped, which is really
strange.

I didn't find a description of this bug (I suspect ld more than gcc,
but...).
You may try to use another binutils and/or gcc version, as suggested....
