Warn the user about the usage of output/target as the root filesystem

A very common mistake done by our users is that they use
output/target/ directory as their root filesystem. Even though this is
loudly documented in our Buildroot manual, people don't read
documentation, so it is not sufficient.

This patch adds a text file named
output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM which explains why
output/target isn't appropriate to use as the root filesystem. The
process is:

 * At the beginning of the build, right after the skeleton has been
   copied, support/misc/target-dir-warning.txt is copied to
   output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM

 * In the filesystem images creation code, this file is removed before
   launching fakeroot, and restored right after that, so that this
   file is not present in the generated root filesystem images.

Note that the file has not been added to the default skeleton for two
reasons:

 * It would have annoying to have in our source tree a file named in
   capital letters inside system/skeleton/

 * The proposed way works even if the user uses a custom skeleton.

lua: don't be fancy when creating shared library

(Possibly) fixes #5354

The lua shared library patch was creating the shared library with
-nostdlib -lgcc for some unknown reason, which most likely is
the reason for the link issue reported in #5354.

Fix it by dropping these arguments, so gcc gets to figure out itself
what dependencies are needed.

python: use default configure commands to get shared build

Commit 3c90f754961c6d99059c0b6d0a66bc797a3c017b made Python use a
special ./configure command in order to avoid --enable-shared
--disable-static being passed, because it was causing issues when
building certain modules for a 64 bits system.

However, not having a shared libpython2.7 library for the host
prevents the libxml2 Python binding to get built.

So instead, we use the default configure command, but we add
--enable-static which is needed for Python to build correctly.

Note that we tested the build of Python on a 64 bits host as well as
the build of Python for a 64 bits target, and both went fine, with all
modules built properly.

mesa3d: requires host-libxml2 and host-python to generate some files

mesa3d now generates some C files at build time (related to the OpenGL
API) from XML files. This generation process is done using Python
scripts that require the libxml2 Python module.

libatomic_ops: bump to version 7.2

The 1.2 we were using doesn't build on ARM Thumb platforms:

  http://autobuild.buildroot.org/results/94ef6be7dcb31021462e7313724217627d4b29df/build-end.log

Moreover, the 7.2 version is the one used by Debian/Ubuntu, and it has
been tested to build fine with the two packages that depend on
libatomic_ops: libdrm and pulseaudio.

gsl: fix build on !i386 uClibc

uClibc pretends to implement <fenv.h> as it installs the header, but
in practice, it only implements the functions for i386. This makes gsl
unhappy as it detects fenv.h, but then cannot use the fenv functions.

dbus: uses fork(), requires MMU

In order to solve
http://autobuild.buildroot.org/results/34f6843137efda20626af72714c110280ec577d7/build-end.log,
this patch makes the D-Bus package as well as all the packages that
select the D-Bus package 'depends on BR2_USE_MMU'.

In addition, for the specific case of gvfs, the missing
BR2_TOOLCHAIN_HAS_THREADS dependency is added (threads are required by
D-Bus, so they are also required by gvfs which selects D-Bus).
