python: convert to autotargets, bump to 2.7.1, many improvements This commit does a number of changes and improvements to the Python interpreter package : * It converts the .mk file to the AUTOTARGETS infrastructure. Even though Python uses only autoconf and not automake, the AUTOTARGETS is a fairly good fit for the Python interpreter, so we make use of it. * It bumps the version to 2.7.1. As this is a minor release compared to 2.7, there are no particular changes needed because of this bump. All changes done to the package are cleanups and improvements unrelated to the version bump. * It uses the system libffi. Until now, Python was building its own libffi (a library used by interprets to build code that makes function call at runtime). Using the Python internal libffi was not working as Python was not passing the appropriate arguments down to libffi ./configure script. And it sounded better to use a system-wide libffi, that could potentially be used by other packages as well. This libffi is needed for the ctypes Python module. * Remove all "depends on BR2_PACKAGE_PYTHON" by moving all Python-related options under a "if BR2_PACKAGE_PYTHON ... endif" condition. * Make the installation of pre-compiled Python modules (.pyc) the default, since they are smaller and do not need to be compiled on the target. It is still possible to install uncompiled modules, or both the uncompiled and pre-compiled versions. * The options to select the set of Python modules to compile has been moved to a submenu. * The codecscjk (Japanese, Korean and Chinese codecs) module is no longer enabled by default. * The commented options for gdbm and nis in Python have been removed. Those were not supported, so let's get rid of unused code. * The option for the tkinker module in Python has been removed, since we don't have a package for Tk in Buildroot. * Options for the bzip2, sqlite and zlib modules have been added, since those modules have external dependencies. * The set of patches has been completely reworked and extended, with more fine-grained patches and newer functionalities. The patches are split in two categories: - Patches that make various modifications to the Python build system to support cross-compilation or make some minor modifications. Those patches are numbered from 0 to 100. - Patches that add configuration options to the Python build system in order to enable/disable the compilation of Python extensions or modules (test modules, pydoc, lib2to3, sqlite, tk, curses, expat, codecs-cjk, nis, unicodedata, database modules, ssl, bzip2, zlib). These patches are numbered from 100 to 200. All features of the previous four patches are preserved, but they are organized differently and the patches have been renamed. This makes it difficult to see the differences from the existing patches. * The host Python interpreter is now installed in $(HOST_DIR), since it is used to build third party Python modules. * The BR2_PACKAGE_PYTHON_DEV option is removed since BR2_HAVE_DEVFILES already does the necessary work. * The "make -i install" workaround introduced by Maxime Ripard is no longer needed. It was caused by the compilation of the tests that required the unicodedata module (which wasn't built in the host Python interpreter). Since we no longer compile the Python tests, the problem doesn't exist anymore and we can avoid this "-i" option. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

Add support in Python build system to specify host tools
Python needs a Python interpreter and a "pgen" program to build
itself. Unfortunately, the Python build system assumes that it can use
the interpreter and pgen program it has just built to build
itself. Obviously, this cannot work in cross-compilation mode since
the interpreter and the pgen program have been built for the target.
Therefore, this patch adds support in the Python build system for the
new PYTHON_FOR_BUILD and PGEN_FOR_BUILD variables, so that we can
point Python ./configure script to the Python interpreter and pgen
program that have been previously built for the host.
Patch ported to python2.7 by Maxime Ripard <ripard@archos.com>, and
later significantly reworked by Thomas Petazzoni
<thomas.petazzoni@free-electrons.com>, with some inspiration taken
from the Python patches of the PTXdist project.
