After a little bit of confusion I could do it. The command had to be run 
from <obj-dir>/gcc and not from <obj-dir>

Here http://matwei.callisto.twam.info/fixunsdfsi.tar.gz is the complete 
file. The interesting lines are

        ldi r18,lo8(0xffffffffcf000000)
        ldi r19,hi8(0xffffffffcf000000)
        ldi r20,hlo8(0xffffffffcf000000)
        ldi r21,hhi8(0xffffffffcf000000)

And there seems to be 64Bit-Int's instead of 32Bit-Int's which should be 
there. Right?

I think we now know what causes the error. But now: How to fix it? I can 
compile the gcc on a 32 Bit box and then put it to my desktop. But that 
can't be the solution. Do I have to fix the lo8()... "functions" of the 
assembler?

What?
