Updated Python 3.x.

- updated to version 3.2.3
 - fixed version numbers in setup-hook.sh
 - sort input variable list alphabetically
 - tk support needs x11 support as well
 - deleted obsolete version 3.1

Furthermore, all CPPFLAGS and LDFLAGS required to find the build inputs are now
explicitly passed to ./configure. The python 3.x build systems tries to ignore
the environment as much as possible to provide deterministic builds. This means
that our magic environment variable stuff won't work, and previously built
python3 binaries lacked all kinds of extensions, such as zlib, etc.
