Python's build scripts prefer ncursesw, and if it is detected
it will be used.
The problem will occur when linking, since ncursesw libs may not be
installed if not added as deps, but the sources will be compiled
against ncursesw.
Reference from Python's HISTORY file:
Patch #1428494: Prefer linking against ncursesw over ncurses library.

This mostly helps to avoid confusion when modules are cross-compiled.
Otherwise build folders are named with the host's platform name.

This will reduce the bloat when users will want to compile in their
Python C extensions.
There will be a initial bloat (several kb) if just Python
is installed, but that will be compensated when users will add more
C extensions.
During the build we also have to add Python's PKG_BUILD_DIR
so that the shared lib is found when compiling Python's
built-in C extensions.

The target's PYTHON_INC_DIR should take precedence over the host's
include dir when cross-compiling.

Seems that the Python C extensions were being
(or at least trying to be) build using '/usr/include' as the first
include folder.
Seems this issue was already fixed on MacOS X and now we've extended
it for our case.

Seems that this allows some goofs, because some files
silently do not get copied and the build succeeds, even though
it shouldn't.

Seems that if you add a package folder this would also
include the compiled python files which increases fw size.

According to PEP394 (http://legacy.python.org/dev/peps/pep-0394/)
the 'python' command should refer to 'python2'.
In our case, this means we should reboot the old python package.
We could rename the package name to python2, but that would
just complicate things a bit with other packages, and
since we're doing this reboot, such a complication would be
unnecessary.

Some notes:
- Python 3 (at least version 3.4) is pretty cross-compiler-friendly,
so a lot of patches were thrown away.
- Arguments below were moved to ./files/config.site file, and disabled
ac_cv_have_chflags=no \
ac_cv_have_lchflags=no \
ac_cv_py_format_size_t=no \
ac_cv_have_long_long_format=yes \
ac_cv_buggy_getaddrinfo=no \
- --without-ensurepip added, because the build wants to ensure that
it works; that's a good idea, but for now, it requires special
setup, and we can do that later
- --without-pymalloc added, becase in Python 3, modules are suffixed
with m; e.g. so some paths are python3.4m instead of python3.4
all this is detailed here:
http://legacy.python.org/dev/peps/pep-3149/
Maybe it will be a good idea to re-add this back

Make python-mini the top-level and default Python package.
Make the other packages subpackages of the top-level python package.
Make old python package the python-full package.
Note: at this point, this package can be split/renamed to
python-legacy should anyone need Python 2. After this commit
it's going to be Python 3 all the way.
