Target 'init/modules.order' does not exist, during i686->x86_64 cross-compilation

Hi there.
I thought about an option to compile x86_64 port of OpenWRT, on i686:

$ gcc --version
gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0
.

Here is my build log:

.
I expected to run generated VM image under qemu-system-x86_64 and on a bare metal x86_64 machine.
