287a88286b graph-depends: rename the variable to pass the max depth
There will soon be new options to the graph-depends script, which we
can only sanely pass via environment variables.

Currently, we use such an environment variable to pass the maximum depth
of the dependency graph; the name of that variable is explicit that it
contains just the depth.

However, there has been so far no release of Buildroot which would make
use of that variable, so no user should have come to rely on it.

Rename that variable so it is less specific, and more generic, so it can
be used to pass more options to graph-depends.

ac93fabb66 infra: Add PRE_*_HOOKS for every step
Add PRE_*_HOOKS to all the different steps through which a package may go.

This will help avoid using POST_*_HOOKS to do tasks that should be done
in the PRE_*_HOOKS of the next step.
Otherwise, when the user would do a make foo-re<step>, this would not do
what was really intented, the POST_*_HOOK of the preceding step not
being executed.

5e3cb35737 manual: fix C++ support in libc case, fix indentation
The manual has this sentence for the dependency on a C library *and* a
toolchain feature:

    foo needs an (e)glibc toolchain, or foo needs an (e)glibc toolchain
    w/ C++ support

And then, just below, the comment text for C++ is just 'C++', not
'C++ support'.

Fix that, and add a bit of indentation too.

4109a20bea manual/configure.txt: fix C++ escaping
For asciidoc, a string like '+these are some words+' will be displayed in
monospace font. Such sequences are identified by searching for a matching
pair of + signs in the same block.

The string 'C++' also contains such + signs. In most cases, this does not
pose a problem and no escaping is necessary. However, if 'C++' occurs twice
in the same block, the + signs will be matched to each other, and asciidoc
formats all text between them as monospaced text. In this case, escaping of
one of these 'C++' occurances is necessary to get the right formatting.

In one place of the manual, there is a sentence that causes such a problem:
    "you only have to tell whether your toolchain supports C++ or not and
    whether it has built-in RPC support. If your external toolchain uses
    the 'uClibc' library, then you have to tell Buildroot if it supports
    largefile, IPv6, RPC, wide-char, locale, program invocation, threads
    and C++."

Commit 082dec8ce4 was based on a patch fixing
this problem in one place of the manual, but was incorrectly changed while
committing.

This patch reverts the incorrect changes in that commit, and solves the
problem correctly.

86a415df8a manual: use one-line titles instead of two-line titles (trivial)
Asciidoc supports two syntaxes for section titles: two-line titles (title
plus underline consisting of a particular symbol), and one-line titles
(title prefixed with a specific number of = signs).

The two-line title underlines are:
Level 0 (top level):     ======================
Level 1:                 ----------------------
Level 2:                 ~~~~~~~~~~~~~~~~~~~~~~
Level 3:                 ^^^^^^^^^^^^^^^^^^^^^^
Level 4 (bottom level):  ++++++++++++++++++++++

and the one-line title prefixes:
= Document Title (level 0) =
== Section title (level 1) ==

=== Section title (level 2) ===
==== Section title (level 3) ====
===== Section title (level 4) =====

The buildroot manual is currenly using the two-line titles, but this has
multiple disadvantages:

- asciidoc also uses some of the underline symbols for other purposes (like
  preformatted code, example blocks, ...), which makes it difficult to do
  mass replacements, such as a planned follow-up patch that needs to move
  all sections one level down.

- it is difficult to remember which level a given underline symbol (=-~^+)
  corresponds to, while counting = signs is easy.

This patch changes all two-level titles to one-level titles in the manual.
The bulk of the change was done with the following Python script, except for
the level 1 titles (-----) as these underlines are also used for literal
code blocks.
This patch only changes the titles, no other changes. In
adding-packages-directory.txt, I did add missing newlines between some
titles and their content.

05754fa01d pkg-python: support host-python dependency different from the python in the target
Some packages need a host-python interpreter with a version different
from the one installed in the target to run some build scripts (eg.
scons requires python2 to run, to build any kind of packages even if
the python interpreter selected for the target is python3).

In such cases, we need to add the right host-python dependency to the
package using the host-python-package infrastructure, and we also want
to invoke the right host python interpreter during the build steps.

This patch adds a *_NEEDS_HOST_PYTHON variable that can be set either
to 'python2' or 'python3'. This variable can be set by any package
using the host-python-package infrastructure to force the python
interpreter for the build. This variable also takes care of setting
the right host-python dependency.

This *_NEEDS_HOST_PYTHON variable only affects packages using the
host-python-package infrastructure.

If some configure/build/install commands are overloaded in the *.mk
file, the right python interpreter should be explicitly called.

If the package defines some tool variable (eg.: SCONS), the variable
should explicitly call the right python interpreter.

[Thomas:
 - fixes to the commit log and documentation suggested by Yann
 - rename the variable from <pkg>_FORCE_HOST_PYTHON to
   <pkg>_NEEDS_HOST_PYTHON, as suggested by Yann
 - do not allow any other value than python2 and python3 in
   <pkg>_NEEDS_HOST_PYTHON, as suggested by Yann.]

5e26da4673 docs/manual: rephrase paragraph about unsupported external toolchains
The ELDK now relies on Yocto, so it no longer has the funky
non-standard way of doing multilib. Also, we didn't mention that Yocto
toolchains/SDK are not suitable for usage with Buildroot. Therefore,
this commit rewords this part of the documentation to explain that
Yocto/OpenEmbedded SDKs cannot be used as external toolchains in
Buildroot, and why.

no longer marked as experimental, a little bit of rewording is

historically supported as the only C library, and that the glibc
support is experimental. We also update the rest of the description to

a524731012 manual: add explanations on limitations about using O=...
Using a relative path for O=... has limitations, since it is interpreted
relative to the Buildroot tree, and thus may lead to unexpected results.

For example, running this:
    make -C buildroot O=my-O

will not create my-O in the current working directory, but as a
sub-directory of the Buildroot tree, here in buildroot/my-O

Explain this in the manual (as is similarly done for BR2_EXTERNAL).
Also add a note that $(O) will be created if missing.

Also change O=.. and -C .. to O=<...> and -C <...> to make it explicit
this is an ellipse, not a relative path.

1de64ec8c0 manual: switch BR2_EXTERNAL examples to use absolute paths
Although it is possible to use relative paths, there are a few pitfalls
when doing so.

To avoid confusion for a (newcoming) user, use absolute paths in the
manual (as is done in examples for $(O)), since it is guaranteed to be
working without corner cases.

f4ea4b9824 Config.in: Add a menu around BR2_EXTERNAL configuration options
To make it clear to the user that these options are external to Buildroot
and no support is provided by the Buildroot community.

With this, there's no need to recommend people to their options inside
a menu, so remove that from the documentation.

Kconfig nicely allows us to hide the menu completely if BR2_EXTERNAL isn't
used, so make use of that to not confuse people. It would be nice if we
could add some help text to explain the BR2_EXTERNAL stuff as well, but
that isn't supported on menus :/

a4239f7fd1 core: introduce the BR2_EXTERNAL variable
This commit introduces the BR2_EXTERNAL environment variable, which
will allow to keep Buildroot customization (board-specific
configuration files or root filesystem overlays, package Config.in and
makefiles, as well as defconfigs) outside of the Buildroot tree.

This commit only introduces the variable itself, and ensures that it
is available within Config.in options. This allows us to use
$BR2_EXTERNAL in a 'source' statement in Config.in.

Following patches extend the usage of BR2_EXTERNAL to other areas
(packages and defconfigs).

In details, this commit:

 * Introduces the BR2_EXTERNAL Kconfig option. This option has no
   prompt, and is therefore not visible to the user and also not
   stored in the .config file. It is automatically set to the value of
   the BR2_EXTERNAL environment variable. The only purpose of this
   BR2_EXTERNAL Kconfig option is to allow $BR2_EXTERNAL to be
   properly expanded when used inside Kconfig source statements.

 * Calculates the BR2_EXTERNAL value to use. If passed on the command
   line, then this value is taken in priority, and saved to a
   .br-external hidden file in the output directory. If not passed on
   the command line, then we read the .br-external file from the
   output directory. This allows the user to not pass the BR2_EXTERNAL
   value at each make invocation. If no BR2_EXTERNAL value is passed,
   we define it to support/dummy-external, so that the kconfig code
   finds an existing $(BR2_EXTERNAL)/package/Config.in file to
   include.

 * Passes the BR2_EXTERNAL into the *config environment, so that its
   value is found when parsing/evaluating Config.in files and .config
   values.

f678e31086 manual: do not generate .pyc files
Python saves a pre-compiled support/scripts/kconfiglib.pyc file
side-to-side with the corresponding .py file.

This does not work if the Buildroot source tree is read-only (but
this is not an error for Python, which keep going OK).

But this may cause issues for out-of-tree builds in case the same
Buildroot source tree is shared by many builds.

Also, 'make clean' currently does not clean this file, and out-of-tree
builds can remove it either, at the risk of causing issues for other
out-of-tree builds running at the same time.

Just tell Python not to generate .pyc files:
  - call the script via python, don't use the sha-bang
  - thus, make the script non-executable, and remove the sha-bang

09dea8e8fb docs/manual: limit the depth of the TOC in the HTML output
The current TOC level is set to 4, which does not mean 'a 4-level deep TOC',
but really means 'a TOC deep to the 4th level', with the first level being
level 0, which means we have:

    12. Appendix
        12.1. Makedev syntax documentation
        12.2. Makeuser syntax documentation
        12.3. Partition table layout description syntax
            12.3.1. The global section
                Properties for the global section

Which a bit too much. And yet, the fifth level is not shown, since we
don't have any! :-/

Limit the depth of the TOC to three levels, which is just enough to be
usefull, yet not cluttered by low-level titles.

2522fa8ed7 pkg-infra: add user-supplied step-hooks
Allow user to supply their own step-hooks by passing a variable
on the make command-line:
    make BR2_INSTRUMENTATION_SCRIPTS=/path/to/my/script

This can be useful to run site-specific actions at each step of the
build process, such as logging installed, removed or modified files,
do sanity checks on installed files...

It is possible to call more than one script, by passing a space-separated
lists of scripts to call.

Also export BUILD_DIR for post-{build,images} hooks, so they do have
a place to store generated files.

Note: this will be more einteresting for the instrumentation of steps,
to come in a later patch.
