Did you tell crosstool-NG to build a soft-float toolchain?
This is in "Target options" ---> "Floating point:" --> "software"

Yes. Painful, isn't it? :-)

Not far. :-) The correct fix is attached. Could you give it a try, please?

BTW, I am collecting fixes both in the 1.3 branch in the repository, but
also as a set of patches in the crosstool-Ng download directory.
