A 'make oldconfig' directly in the build directory should also detect
this properly. If not then this gcc-version is doing something
different.

No, the build system will add the right option for you automatically.

This is strange, seems that this gcc-4.0 does not like this code. On the
other side I'm successfully compiling with 3.4 and 4.1. Can you try
another ARM cross-compiler? Is there something special about your
version for your hw?
