Creating busybox image fails

[santifa]

I tried to run the vmm-reference with the busybox image.
Building the image fails with Kernel config not found.

The config.sh sets the variable only if uname -i returns a known platform.
I tried a debian buster and a arch linux where both answers with unknown.

I would recommend to add a flag for choosing the hw platform or use lscpu | grep <hw-platform>.
Following the man page man 2 uname only uname -m is safe and meaningful.

I have another question: Is it possible to run block devices with a valid grub partition directly?

Thanks for the hard work.
