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.

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.

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]

wpa_supplicant isn't API compatible with gnutls3 so remove support.
It's probably hardly used since openssl is far more common, and
wpa_supplicant can use its internal routines if it's not available.

keyutils builds on neither avr32, nor microblaze (probably because
the toolchains used for those archictectures are way too old), with:
..../microblazeel-unknown-linux-gnu-gcc -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE
-D_FILE_OFFSET_BITS=64 -I. -DPKGBUILD="\"2012-12-27\"" -DPKGVERSION="\"keyutils-1.5.5\""
-DAPIVERSION="\"libkeyutils-1.4\"" -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE
-D_FILE_OFFSET_BITS=64 -pipe -Os -g -Wall -Werror -UNO_GLIBC_KEYERR -o keyutils.o -c keyutils.c
cc1: warnings being treated as errors
key.dns_resolver.c: In function 'main':
key.dns_resolver.c:690: warning: dereferencing type-punned pointer will break strict-aliasing rules
Fixing with -fno-strict-aliasing only partially solves the issue for these
two archs, since the C library does not export the resolver symbols so the
link fails down the road...
- on microblaze, glibc-2.3.6 is tool old and does not set these symbols
as GLOBALs;
- on avr32, uClibc does not have these symbols.
It is much more easy to just disable keyutils for avr32 and microblaze.
Fixes both (avr2, microblaze):
