If it does, please could you upload the object file from the compilation (ie test.o), and also let us know the full linker command line that is being invoked by gcc ? Additionally, how was the toolchain you are using configured ? Finally, please can you try out the uploaded patch. If I am right then it will fix the problem, but at the moment this is just a guess.
