Like above.
See this is what happens for me:

So, I can only imagine it is your toolchain that is letting you down.
What is your host machine? Can I send you a new toolchain? (Mine are only
good for building kernels - they have no libraries - they are build by a
script I got from Segher Boessenkool.)
