Bump buildroot to 2020.08.2

Release notes: https://git.busybox.net/buildroot/tree/CHANGES?h=2020.08.2

Additional patches being carried:
 - a84aaae package/dropbear: Add separate configuration option for dropbear server
 - 050d2a5 Separate target-building make targets from image-building make targets

Additionally, glibc 2.31 from buildroot 2020.08 is adding around 10MB more storage
use on the rootfs, which in practice means around 1MB larger squashfs image. Bump
PNOR layout package version to address that.

OpenPOWER Firmware Build Environment

The OpenPOWER firmware build process uses Buildroot to create a toolchain and build the various components of the PNOR firmware, including Hostboot, Skiboot, OCC, Petitboot etc.

Documentation

https://open-power.github.io/op-build/

See the doc/ directory for documentation source. Contributions are VERY welcome!

Development

Issues, Milestones, pull requests and code hosting is on GitHub: https://github.com/open-power/op-build

See CONTRIBUTING.md for howto contribute code.

Building an image

To build an image for a Blackbird system:

git clone --recursive https://github.com/open-power/op-build.git
cd op-build
./op-build blackbird_defconfig && ./op-build

There are also default configurations for other platforms in openpower/configs/. Current POWER9 platforms include Witherspoon, Boston (p9dsu), Romulus, and Zaius.

Buildroot/op-build supports both native and cross-compilation - it will automatically download and build an appropriate toolchain as part of the build process, so you don't need to worry about setting up a cross-compiler. Cross-compiling from a x86-64 host is officially supported.

The machine your building on will need Python 2.7, GCC 6.2 (or later), and a handful of other packages (see below).
