17902f5b16 manual/adding-packages-perl.txt: remove the trailing slash sign from description of PERL_SITE variable
Since the trailing slash is stripped from $($(PKG)_SITE) by pkg-generic.mk:

$(call DOWNLOAD,$($(PKG)_SITE:/=)/$($(PKG)_SOURCE))

so it is redundant.

aa0c8be4e2 docs/manual: enhance doc for BR2_TOOLCHAIN_HEADERS_AT_LEAST_X_Y
The BR2_TOOLCHAIN_HEADERS_AT_LEAST_X_Y symbols can be used to denote the
lowest required kernel headers version, but also the highest supported
version. Document that.

Use the `...` construct instead of +...+ used eveywhere else, otherwise
asciidoc would render +<=+ to the ⇐ arrow, while `...` does no rendering
at all.

5af28fe6a1 pkg-autotools: add support for <pkg>_AUTORECONF_ENV
This commit improves the autotools-package infrastructure to support a
<pkg>_AUTORECONF_ENV variable, which allows a package maintainer to
pass additional variables in the environment of the autoreconf
execution. This is useful in the situation where configure.ac contains
shell commands using environment variables that are only executed when
autoreconf is run.

734b34f520 infra/pkg-perl: add possibility to pass extra env at configure time
Some perl packages may use environment variables as a hint to know how
to be configured.

That's for example the case for perl-net-ssleay that uses
OPENSSL_PREFIX, if it is set in the environment, as the prefix to
openssl.

Add a new variable that packages can set if they need extra environment
variables. Update the manual accordingly.

54456cc698 infra: consistently use double dollar signs inside inner-xxx-targets
The inner-xxx-targets in the buildroot package infrastructures are
evaluated using $(eval) which causes variable references to be a bit
different than in regular make code. As we want most references to be
expanded only at the time of the $(eval) we should not use standard
references $(VAR) but rather use double dollar signs $$(VAR). This includes
function references like $(call), $(subst), etc. The only exception is the
reference to pkgdir/pkgname and numbered variables, which are parameters to
the inner block: $(1), $(2), etc.

This patch introduces consistent usage of double-dollar signs throughout the
different inner-xxx-targets blocks.

In some cases, this would potentially cause circular references, in
particular when the value of HOST_FOO_VAR would be obtained from the
corresponding FOO_VAR if HOST_FOO_VAR is not defined. In these cases, a test
is added to check for a host package (the only case where such constructions
are relevant; these are not circular).

Benefits of these changes are:
- behavior of variables is now again as expected. For example, setting
  $(2)_VERSION = virtual in pkg-virtual.mk will effectively work, while
  originally it would cause very odd results.

- The output of 'make printvars' is now much more useful. This target shows
  the value of all variables, and the expression that led to that value.
  However, if the expression was coming from an inner-xxx-targets block, and
  was using single dollar signs, it would show in printvars as
    VAR = value (value)
  while if double dollar signs are used, it would effectively look like
    VAR = value (actual expression)
  as is intended.
  This improvement is for example effective for FOO_DL_VERSION, FOO_RAWNAME,
  FOO_SITE_METHOD and FOO_MAKE.

The correctness of this patch has been verified using 'make printvars',
'make manual' and 'make legal-info' before and after applying this patch,
and comparing the output.

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.

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.]
