When cross-compiling, we do not need to add runtime lib dirs.
Also, the cross compilers that are used on OpenWRT do not support
the '-R' option, which causes build failures.
These build failures existed before, but were not noticed,
because it fails only on some setups.
This is because Python's `setup.py` does a lot of voo-doo
automagic that needs handling for some cross-compilation cases.

Packetize some Python modules to reduce size of the overall Python package.
Basically, a new package is introduced, call `python-light`,
and everything that's extra (or big) is put in other packages.
The `python` package becomes a metapackage that installs `python-light`
along with the rest of the packages.
Base work started by Jan Čermák.

When distutils are copying scripts, path to Python interpreter is adjusted.
This does not work well in OpenWrt buildroot, because the path is adjusted
to absolute path to host Python then. This patch simply disables the
adjusting of the path.

Try to reduce the amount of change in this patch, since it removes
a lot of stuff, when we could just 'ifdef' that stuff out, with 2 lines.
The buildroot project does something similar like this:

This module is not necessary in OpenWrt because the functionality it
provides (i.e. installation of setuptools and PIP) is ensured by
python-pip and python-setuptools packages.

Seems when cross compiling on x86_64 Debian (most likely Ubuntu too)
the host's paths will be added too causing build failures for some extensions.

Python packs some pip installation script during the build,
which looks like a better idea to use for the python-pip
and/or python-setuptools packages.

That would allow for files (in filespecs) to be indented.
As it is now, the files need to be added at the begginning of the line.

Seems that using += adds a space in the PYTHONPATH.
Could be some other error, but at least this way
it's sure to not leave any spaces.
Thanks @Xuefer.

Some symbols are not found (tgetnum and BC).
Looks like the termcap lib, which should be in libncurses(w)
but maybe some build param would be required.

Redefine python-full as all-pages-minus-a-few-that-don't make sense.
Remove all other packages.

This fix is quite critical since it fixes copying the libpython shared lib.
The previous source folder we've used is ok, it has the shared lib,
but libpython2.7.so is not a symlink of libpython2.7.so.1.0, but
rather a copy of it.
Which means that libpython2.7.so takes twice as much space
on the target's flash.

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.
