The given patches weren't enough :-(   The resulted GNU linker complained
about not finding the output format etc.  A quick "how these things were 
done
in 'alpha', 'i386' etc." comparison revealed that also the 'ld/emulparams'
directory required the following patch in the current 
'binutils-2.17.50.0.3' :

After adding this the produced binutils gave right labeled executables and
more importantly the crosscompilers to the 'x86_64-freebsd6.1' target
could be built, giving seemingly OK shared libraries with the following:

kai@Dell:/data1/home/src/gcc-4.0.3/build/gcc> readelf -h libgcc_s.so.1

output got via the 'readelf -h'...
