Okay, since you built the toolkit yourself, it is very probable that
your glibc is also built with FPA hardfloat, so the following might
not actually help; but as a quick hack, you can try to edit the file:

  /opt/crosstool2/lib/gcc-lib/arm-linux/3.3.3/specs

and replace the line:

  %{msoft-float:-lfloat} -lgcc

with:

  -lgcc

It may be better to rebuild your toolkit using softfloat as default,
though.  Try replacing the softfloat patch in crosstool's
patches/gcc-3.3.3 directory with this one:

http://www.andric.com/cross/patches/gcc-3.3.2-arm-softfloat.patch.bz2

(Should apply to gcc 3.3.3 sources too, I hope)
