Fixes #176. It looks like the root cause of that regression is that objdiff 3 now infers that 0-size symbols are larger than they really are if junk(?) data comes right after them, so objdiff guess that these 0x68 bytes are a function called ".text". objdiff 2 just skipped over it because it had size 0 and unknown type.
Since it's not clear if this object is even valid I think a quick fix that just avoids the build error is fine in this case so that it can be viewed.
