python, python-native upgrade from 2.6.5 to 2.6.6

Removed these patch:
    python-native-2.6.5/00-fix-bindir-libdir-for-cross.patch
    python/00-fix-bindir-libdir-for-cross.patch

The upstream code has changed, and it does not need the above 2 patches
(fixes) anymore.

Patches rebased to the newer code:
   python/01-use-proper-tools-for-cross-build.patch
   python/04-default-is-optimized.patch
   python/06-avoid_usr_lib_termcap_path_in_linking.patch
   python/99-ignore-optimization-flag.patch
