python3: bump to 3.4.0rc1

This commit bumps the Python3 package to use Python 3.4.0rc1.

About the patches:

 * The patches below 100 are significantly changed, because like for
   Python 2.x, a good number of improvements have been made in the
   upstream Python for cross-compilation. Therefore, almost all of
   these patches have been modified.

 * All the patches above 100 are simply updated for Python 3.4.0, with
   a small refactoring for the handling of test modules.

The details of the python3.mk changes are:

 * --without-ensurepip to tell Python to not use PIP at build time.

 * Many environment variables are no longer passed, they were specific
   to our cross-compilation patches

 * The fixup of the LIBDIR in the Python Makefile is no longer needed
   since Python has switched to _sysconfigdata.py for distutils
   configuration instead of parsing the Makefile.

 * A new post patch hooks touches the two files generated by pgen to
   make sure they are newer than the pgen sources, which ensures pgen
   is not built/executed.
