Consider the second chapter: "starting-up", as a tutorial.
Assuming that, using.txt only contains the very first commands used to get
configure and build its very first target system.
So, the following subsection from using.txt have been to common-usage.txt:
- Offline builds
- Building out-of-tree
- Environment variables

The new skeleton of the manual as it has been thought:
1. About Buildroot:
Presentation of Buildroot
2. Starting up:
Everything to quickly and easily start working with Buildroot
3. Working with Buildroot
Basics to make your work fitting your needs
4. Troubleshooting
5. Going further in Buildroot's innards
Explaination of how buildroot is organised, how it works, etc
6. Developer Guidelines
7. Getting involved
8. Contibuting to Buildroot
9. Legal notice
10. Appendix
It is easy to distinguish two parts in this plan:
- Sections 1 to 4 mainly address people starting with Buildroot
- Sections 5 to 10 are more focused on how to develop Buildroot itself
Most of the existing sections have just been moved in the hierarchy,
few were split and dispatch in, what i think was the relevant section,
and numerous others have been created.

Fixing linking time error with certain toolchains. The issue caused by a missing explicit linking to

We need more recent versions of config.guess and config.sub in order
to support the aarch64 architecture. Otherwise, all autoconf packages
fail to build with failures like:
http://autobuild.buildroot.org/results/abcdbe1aaf1c203c82dc3e4ec8c002b9b9e550e0/build-end.log
We take this opportunity to turn the config.* patches into proper Git
patches, and note which Git commit of the config.git repository we
used as the original source.

Xtensa is a configurable processor architecture, which allows to define
additional instructions and registers. The required variant specific
information for the toolchain is delivered in an 'overlay' file, which
needs to be 'untarred' to the corresponding directories after the
source is installed and patched.
This patch provides support for binutils, gcc, and gdb with a very
limited changes to the build scripts. These additions are only executed
for the Xtensa architecture and have no effect on other architectures.

Variant'].

The Xtensa architecture had been removed because it required special
handling and depended on additional directories and files that became
obsolete over time. This change is more aligned to other architectures.

As suggested by Yann E. Morin, there is a better way than our current
big Config.in.common to define the gcc mtune, mcpu, march,
etc. values. We can split the setting of those values in each
architecture file, which makes a lot more sense.
Therefore, the Config.in file now creates empty kconfig variables
BR2_ARCH, BR2_ENDIAN, BR2_GCC_TARGET_TUNE, BR2_GCC_TARGET_ARCH,
BR2_GCC_TARGET_ABI and BR2_GCC_TARGET_CPU. The values of those
variables are set by the individual Config.in.<arch> files. This is
possible because such files are now only conditionally included
depending on the top-level architecture that has been selected.
