It can be useful to have different configuration use the same post-build
and/or post-image scripts as they share a common infrastructure, but yet
have minor differentiation.
This option allows passing zero or more additional arguments to each
post-build or post-image script.
The same set of extra arguments are passed to all scripts, it is not
possible to pass different arguments to each script.
[Peter: fix help text, post-image gets called with the images dir]

This makes it possible to put empty directories in the overlay.
Thanks to Aras Vaichas for pointing that out.

The order of the solutions to customize the root filesystem is
changed: we now mention the post-build script mechanism *before* the
custom root filesystem skeleton mechanism, because the former is
preferred over the latter.
In addition to this, we give a few more details about direct
customization of the root filesystem in output/target, and about the
custom target skeleton solution.

The filesystem overlay is a tree that is copied over the target fs
after building everything - which is currently usually done in the
post-build script.

Several projects use the kernel style O=<dir> syntax to build out of tree,
and atleast uClibc doesn't check that it was explictly passed on the command
line, so setting it in the environment breaks the build.

Support scripts (in support/) may need to parse the .config file, so give
them an easy access to it, by exporting BUILDROOT_CONFIG with the fully-
qualified path to .config.
Also, post-build scripts may need to reference a few locations, so export
those, too.
Note: we export both O and BASE_DIR. Although they are the same, BASE_DIR
is used internally, while O is used on the command line, which makes it a
bit ambiguous to know which to use. As users use O= on the command line,
they will probably tend to use that in their post-build scripts.
Update doc accordingly.

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.

This directory groups the following elements:
* the default root filesystem skeleton
* the default device tables
* the Config.in options for system configuration (UART port for
getty, system hostname, etc.)
* the make rules to apply the system configuration options
Even though the skeleton and device tables could have lived in fs/, it
would have been strange to have the UART, system hostname and other
related options into fs/. A new system/ directory makes more sense.
As a consequence, this patch also removes target/Makefile.in, which
has become useless in the process.
[Peter: fixup TARGET_SKELETON settings / documentation to match]
