I have a toolcahin working quite well: gcc-4.1.2 binutils-2.17, generic arm softfloat supporting EABI. This works with kernel and userspace well. Only on u-boot it fails at the final stage:

Does somebody have an advise or tip for me how to fix this? I digged around and added an (empty) raise() function to my u-boot, which compiles fine.
