i'm trying to do it now, i think we need to pass --enable-multilib when 
configuring cross gcc for x86-64, however it fails with error on 
gcc-3.3.2, it says something about ld skipping incompatible libraries 
when linking with -lc etc ??? i've managed to built full x86-64 
toolchain, but only with --disable-multilib options. well i'll try a 
snapshot of gcc-3.4.0, maybe that's different.
