Issue #14499: Fix several problems with OS X universal build support: 

1. ppc arch detection for extension module builds broke with Xcode 5
    2. ppc arch detection in configure did not work on OS X 10.4
    3. -sysroot and -arch flags were unnecessarily duplicated
    4. there was no obvious way to configure an intel-32 only build.

A second reason for using frameworks is that they put Python-related items in
only two places: "/Library/Framework/Python.framework" and
"/Applications/Python <VERSION>" where ``<VERSION>`` can be e.g. "3.3",
"/Applications/Python <VERSION>" where ``<VERSION>`` can be e.g. "3.4",

Python from a binary distribution if they want to get rid of it again. Moreover,
