Bug 257407

When I try to cross-compile i386 and amd64 architecture under amd64 build host.
If I have a good chance to finish kernel compiling and linking then process fails on compiling of kernel modules.

From last update of CURRENT sources. Now I have different issue with compile procedure of kernel.
