python3 installs would fail while linking
prefix/share/python3/easy_install to easy_install3 if the target already
existed, which caused any python3 installation after the initial to
fail. Skip linking if the symlink already exists.
This takes care of the issue described here (recognizing gdbm 1.9.x
databases): http://www.gossamer-threads.com/lists/python/bugs/942749
The patches are already in their respective upstream repositories, so
they will presumably be included in the next Python 2.7.x and 3.2.x
releases.

Based off of the Python 2.6.5 formula. Minor comment tweaks along with adding
an extra performance flag that works under both gcc and LLVM.
