Updates the hook kernel config, and fixes makefile (#42)

## Description

This does two things (apologies, but one needed fixing for the other):
- Adds a `local` build to the Makefile, we shouldn't need to always push a kernel kconfig to a registry to build a local kernel
- Updates the readme to reference the correctly tagged kconfig kernel and displays usage of local build.
- Adds intel GFX support

## Why is this needed

Currently an intel Nuc / Gigabyte brix will hang on boot

Fixes: #

#38 

## How Has This Been Tested?
<!--- Please describe in detail how you tested your changes. -->
<!--- Include details of your testing environment, and the tests you ran to -->
<!--- see how your change affects other areas of the code, etc. -->
Ran locally on a nuc

## How are existing users impacted? What migration steps/scripts do we need?

<!--- Fixes a bug, unblocks installation, removes a component of the stack etc -->
<!--- Requires a DB migration script, etc. -->


## Checklist:

I have:

- [x] updated the documentation and/or roadmap (if required)
- [ ] added unit or e2e tests
- [ ] provided instructions on how to upgrade

 ## Modify the kernel
 
-The Makefile can build a docker environment to configure a new kernel.
+The Makefile can build a docker environment to configure a new kernel, it can generate a docker image and push it to the tinkerbell repository or build a local image.
+
+**NOTE** This builder makes use of the docker `buildx` functionality that can be enabled with `docker buildx create --use`
+
+Making a **multi-arch** image and pushing to the quay.io repository:
 
 ```
 make kconfig
 ```
 
+Making a **local** image (multi-arch isn't supported locally, so generate the kernel config for your local architecture [amd64/arm64])
+
+```
+make kconfig_amd64
+```
+
 We can now run this image:
 
 ```
-docker run --rm -ti -v $(pwd):/src:z tinkerbell/kconfig
+docker run --rm -ti -v $(pwd):/src:z quay.io/tinkerbell/kconfig
 ```
 
 If modifying the config for a different architecture, it is best to specify the platform to
 avoid any surprises when attempting to build the kernel later.
 
 ```
-docker run --rm -ti -v $(pwd):/src:z --platform=linux/arm64 tinkerbell/kconfig
+docker run --rm -ti -v $(pwd):/src:z --platform=linux/arm64 quay.io/tinkerbell/kconfig
 ```
 
 We can now navigate to the source code and run the UI for configuring the kernel:
