I built your exact defconfig in a Docker container that has Debian
Jessie 8.10 installed, and it worked just fine for me. I only had an
issue way after the toolchain build, when building the kernel, because
your defconfig lacks:

  BR2_LINUX_KERNEL_NEEDS_HOST_OPENSSL=y

But other than that, it builds fine. So I suspect there is something
wrong/special in your environment. As I can't reproduce, you'll have to
investigate a bit yourself I'm afraid.

Best regards,

Thomas
