Andrey Smirnov 6e6e8d37b5 package/python3: bump to 3.6.2
Bump Python3 version to 3.6.2.

Patches dropped:

"Support PGEN_FOR_BUILD and FREEZE_IMPORTLIB_FOR_BUILD"

Rationale: With commit 9d02f562961efd12d3c8317a10916db7f77330cc, code
generation step of building CPython now became explicit (instead of
always performed as a part of 'make' invocation) and more granular. We
no longer need to use Parser/pgen at all and tricking the build system
into using different Programs/_freeze_importlib can be done as a part
of recipe.

Additional info about the build change can be found at

Subject: [PATCH] Adjust library/header paths for cross-compilation
When cross-compiling third-party extensions, the get_python_inc() or
get_python_lib() can be called, to return the path to headers or
libraries. However, they use the sys.prefix of the host Python, which
returns incorrect paths when cross-compiling (paths pointing to host
headers and libraries).
In order to fix this, we introduce the _python_sysroot, _python_prefix
and _python_exec_prefix variables, that allow to override these
values, and get correct header/library paths when cross-compiling
third-party Python modules.
