Cross compile Debian kernel in chroot environment, start from armel for stretch/sid

Purpose

To make a chroot cross build environment especially for kerenel under Debian. Currently working for Stretch/Sid on armel (marvell).

Step0, make a chroot environment. The script will debootstrap a minimal rootfs for cross compiling.

$ sudo ./0_mkchroot.sh

Step1, get source code from Debian Kernel SCM. You could either choose to run this out-of or within chroot

$ sudo ./1_chroot_get-source.sh

or

$ sudo ./chroot_shell.sh
## Below is under chroot environment
$ ./debian-kernel-cross/sid/1_chroot_get-source.sh

Step2, cross compile. You could either choose to run this out-of or within chroot.

$ sudo ./2_chroot_build-deb.sh

or

$ sudo ./chroot_shell.sh
## Below is under chroot environment
$ ./debian-kernel-cross/sid/2_chroot_build-deb.sh

If something goes wrong, you can check up the Step2 script and start from the the blocked command again.

The cross compiled armel kernel is confirmed to working on:
