wavpack: fix broken link on newer binutils

Newer versions of binutils (2.22+) default to --no-copy-dt-needed hence
all the used libraries must be explicitly named.
This is accounted for in the source configure script but not in the
compiled form so we just need to autoreconf it.

[Peter: add comment why autoconf is needed]

docs/manual: add a new 'Details on Buildroot configuration' section

As discussed with Samuel Martin, there are a few questions about some
Buildroot configuration aspects that come very often on the IRC
channel and on the mailing-list. Topics such as the /dev management
and init systems are often raised.

Therefore, this patch adds a new section that provides details about
the Buildroot configuration possibilities. It does not aim at
replacing the help text of each configuration option, but rather to
complement them by providing more background. Having those
informations in the manual will also make it easier for us to point
newcomers to the right place in the documentation when they have
questions.

Note that this section will replace the "Embedded basics" section that
comes way too late in the manual. This is done in a followup commit.

docs/manual: add details on toolchain configuration

This commit adds a new section

 Working with Buildroot
  -> Details in configuration
    -> Cross-compilation toolchain

that gives a lot of details about our three toolchain backends. It
takes some elements that were previously later in the manual in
"Embedded basics" and in "External toolchain" and combines them with
more details about internal backend and Crosstool-NG backend.

The "Embedded basics" section becomes empty and is therefore
removed. A few elements have been lost in the process, but they were
considered to not be really useful, especially located so far in the
manual.

docs/manual: remove FAQ entry about 'depends on' vs. 'select'

The FAQ is before the section on package development, and only covers
user issues, not developer issues, so the FAQ entry about 'depends on'
vs. 'select' really doesn't have its place here.

And the 'depends on' vs. 'select' issue is already covered in a later
section, see
http://buildroot.org/downloads/manual/manual.html#depends-on-vs-select.

docs/manual: remove incorrect prerequites

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.

docs/manual: do not suggest to create a symlink for shared download directory

Creating a symbolic link for the download directory is really not a
useful suggestion, since we have the much better solution of the
BUILDROOT_DL_DIR environment variable. So emphasize this solution
instead, and remove the suggestion of the symbolic link.
