Similar to the --with-pc-path option. It works just like the existing
PKG_CONFIG_SYSROOT_DIR environment variable, but compiled in.
The environment variable overrides this default setting if set.
This way we don't need to pass PKG_CONFIG_SYSROOT_DIR in the environment
when building for the target, and it is easier to reuse pkg-config outside
BR (E.G. for the SDK) without having to setup special environment
variables.

Fixes gst-plugins-bad build, if gstreamer is installed on host with xml
support, as it uses pkg-config --variable=includedir to find gstconfig.h,
and hence ends up looking at the host version.

Now that we have a proper host-python package, use that one instead of
whatever might be available on the build host. Also don't overwrite
the host-python package version variable and fix dependency list
(xcb-proto is needed for the host).

Some packages (like libxcb) need xml support in host-python in order to

The CMAKETARGETS infrastructure makes adding CMake-based packages to
Buildroot easy. It uses the same set of variables as the autotools
infrastructure, except for autoreconf and libtool stuff which is not
needed. Usage: just call CMAKETARGETS instead of AUTOTARGETS.

By default, zlib installation procedure calls ldconfig, which takes
time uselessly. ldconfig is only useful if you install libraries on
the host (in directories listed in /etc/ld.so.conf, or in /usr/lib or
/lib), so calling it after installing libraries in $(STAGING_DIR),
$(TARGET_DIR) or $(HOST_DIR) is just a lenghty no-op.

Autoconf would append -dirty to it's version number, causing build breakage
with packages explicitly requesting autoconf 2.65, if built in a subdir
of a git tree with uncommitted changes. This is a relatively common
situation when developing on BR.

As pointed out on the list, using sysroot rather than sys-root is less
confusing, as this is how it is referred to in the GCC manual.
So rather than changing BR, patch ct-ng to use sysroot instead.
The next ct-ng release will use 'sysroot' as well by default.

crosstool-ng would normally delete its installation directory before
installing the toolchain to ensure it wouldn't get confused by an earlier

work very well - So get rid of the rm's.

For some reason, tcpdump and libpcap need to have some information
about the kernel version being used. This information is passed using
the ac_cv_linux_vers autoconf variable.
However, the current value is determined using
BR2_DEFAULT_KERNEL_HEADERS which is only defined when an internal
Buildroot toolchain is used. So it would break with an external
toolchain or the Crosstool-NG backend.
According to Mike Frysinger at
http://lists.busybox.net/pipermail/buildroot/2011-January/040861.html,
this value is only used to determine if the kernel version is 0.x, 1.x
or 2.x, so passing ac_cv_linux_vers=2 is sufficient since Buildroot
only supports the 2.6 kernel anyway.

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.

The libffi library provides a portable, high level programming
interface to various calling conventions. This allows a programmer to
call any function specified by a call interface description at

On 0.10.11 the binary-registry was added, on 0.10.12 the libxml2
dependency was dropped when binary-registry was used, on 0.10.18 the
binary-registry was made default, and on 0.10.23 it was the only option.
So, libxml2 is not needed any more for the registry.
