I built my binutils on my own, following the tutorial found at 
http://www.ltc.com/~brad/mips/mips-cross-toolchain/. So I used 
../binutils/configure --target=mipsel-linux \
  --libdir='${exec_prefix}'/mipsel-linux/i386-linux/lib
as configure-settings. How can I set something more special than the 
mipsel-architecture (the vr4100-processors)

Shouldn't I additionally add -msoft-float, because the VR4181A has no 
FP-Coprocessor?
