Marc Herbert ebaa1429f9 xtensa-build-zephyr.py: log ALL "evil" environment differences 
This is a typical example of why environment variables are (a sometimes
necessary) evil: imagine you're trying to reproduce exactly the `west
build` command run by xtensa-build-zephyr.py when building with the
`xt-xcc` toolchain. So you would typically look at the logs, feel lucky
that it shows the extra environment variables used and copy them:

```
XTENSA_TOOLCHAIN_PATH=/srv/home/jenkins/xcc/install/tools
TOOLCHAIN_VER=RG-2017.8-linux
XTENSA_SYSTEM=/home/jenkins/xcc/install/builds/RG-2017.8-linux/cavs...
In dir: workspace/sof; running: west build ...
```

Except this won't work because there's one variable currently missing:
`ZEPHYR_TOOLCHAIN_VARIANT`!

Of course there could be more in the future.

Fix this by leveraging the recent os.environ.copy() added by
commit 8aab18351f ("xtensa-build-zephyr: fix DEFAULT_TOOLCHAIN_VARIANT
spill on next platf") compare it to the current os.environ and show the
difference in a totally generic, non-hardcoded way.

README.docker 

The docker container provided in docker_build sets up a build environment for
building Sound Open Firmware. A working docker installation is needed to run
the docker build container.

Note: In order to run docker as non sudo/root user please run.

sudo usermod -aG docker your-user-name

Then logout and login again.

Quick Start:

First, build the docker container. This step needs to be done initially and
when the toolchain or alsa dependencies are updated.

cd scripts/docker_build

./docker-build.sh

After the container is built, it can be used to run the scripts.

To build for tigerlake:
./scripts/docker-run.sh ./scripts/xtensa-build-all.sh -l tgl
or (may need password test0000 for rimage install)
./scripts/docker-run.sh ./scripts/xtensa-build-all.sh tgl

To rebuild the topology and logger:
./scripts/docker-run.sh ./scripts/build-tools.sh

An incremental sof.git build:
./scripts/docker-run.sh make

Or enter a shell:
./scripts/docker-run.sh bash
