create custom arm64 Debian image

[Andrei Martin <andrei.cos.martin@gmail.com>]

Hi,

I want to customize the kernel for a Debian image for arm64[1], but using the documentation from here[2], I get the following error:

`chroot: failed to run command ‘/usr/bin/env’: No such file or directory`,

while running `cd debian-live-config && make install_buildenv && make`.

Could you guide me in solving this issue? The custom kernel will be used to debug some hypervisor related issues (bhyve on arm64).
