RHEL 6, version 4.4.

Recently, the autoconf macros for libtool started using '/usr/bin/file'
to determine the type of library that is generated by the toolchain.
Packages that use this recent version of the libtool autoconf macros
will fail in a rather dramatic way when /usr/bin/file is not present
on the host: the package will still build but no shared library is
generated, which in turn may cause build failures in other packages
that link with it.
For example, libpng's configure determines that it is not possible to
build a shared library on MIPS64 because the expected output from 'file'
is not present. Therefore, only a static libpng.a is built. Later,
bandwithd links with -lpng but it doesn't use the pkg-config's
Private-Libs (because it's not linking statically) and it doesn't have
access to the NEEDED reference from the shared library. Therefore, it
doesn't link with zlib and fails with
pngrutil.c:(.text+0x55c): undefined reference to `inflate'
We cant use host-file because it is itself an autotools package and is
itself using libtool, so this would be a chicken-n-egg problem. Besides,
the libtool script really wants to call /usr/bin/file, so it would not
even find our host-file anyway.
So, just require that '/usr/bin/file' is present on the host.

This patch reworks the requirements section of the manual as follows:
- some general rewording
- move configuration editor dependencies above the download tools, as this
is the first thing people come in contact with.
- move sentence regarding -dev packages to configuration editor dependencies
and restrict to 'libraries'.
- clarify the download tools part.

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.

To generate the manual, you need a few tools. If these are not present,
pretty cryptic error messages are given.
This patch adds a simple check for these dependencies, before attempting to

awk, bison, flex, makeinfo, gettext should be built as dependencies of
packages when needed. In practice, even the toolchain build doesn't
need any of these, and only a few packages do require them.
It is not needed to list gzip and bzip2 since they are already checked
through ${DL_TOOLS}: whenever a package needs gzip or bzip2 for its
extraction, the dependency is added.

The development files for zlib or netpbm are not needed, and neither
is python-xcbgen. None of these are present in the chroot used in the
autobuilders, and anyway if those would be needed, it would be a
Buildroot bug and not something to be mentionned in the documentation.
