python3: add _PYTHON_HOST_PLATFORM env var when cross-compiling C extensions
This mostly helps to avoid confusion when modules are cross-compiled.
Otherwise build folders are named with the host's platform name.

The target's PYTHON3_INC_DIR should take precedence over the host's
include dir when cross-compiling.

python3: enforce the existence of files in the filespecs
Seems that this allows some goofs, because some files
silently do not get copied and the build succeeds, even though
it shouldn't.

python3: reduce bloat by removing *.pyo and *.pyc files
Seems that if you add a package folder this would also
include the compiled python3 files which increases fw size.

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
