In particular, fix extension module build failures when trying to use
    32-bit-only installer Pythons on systems with Xcode 4 (currently
    OS X 10.8, 10.7, and optionally 10.6).
    * Backport 3.3.0 fixes to 3.2 branch (for release in 3.2.4)
    * Since Xcode 4 removes ppc support, extension module builds now
      check for ppc compiler support and by default remove ppc and
      ppc64 archs when they are not available.
    * Extension module builds now revert to using system installed
      headers and libs (/usr and /System/Library) if the SDK used
      to build the interpreter is not installed or has moved.
    * Try to avoid building extension modules with deprecated
      and problematic Apple llvm-gcc compiler.  If original compiler
      is not available, use clang instead by default.

There was a window between the write and the chmod where the user’s
password would be exposed, depending on default permissions.  Philip
Jenvey’s patch fixes it.

These files are created by some NFS clients a file is edited and removed
concurrently (see added link in doc for more info).  If such a file is
removed between distutils calls listdir and copy, it will get confused.
Other special files are ignored in sdist (namely VCS directories), but
this has to be filtered out earlier.

may differ between sysconfig and distutils.sysconfig due to
compiler customizations on OS X.  For now, move those vars
into a separate test and skip if the customization has taken
place in distutils.  The long-term solution is to eliminate
having two sysconfig modules.

tailoring for universal builds by factoring out common OS X-specific
customizations from sysconfig, distutils.sysconfig, distutils.util,
and distutils.unixccompiler into a new module _osx_support that can
eventually also be used by packaging.

- fix test_distutils and test_sysconfig test failures by
  aligning sysconfig and distutils.sysconfig tailoring of
  configure variables (as in 2.7)

python executable

The __os_install_macro defines some post-processing activities during an rpm
build; one of the scripts it calls is brp-python-bytecompile, which can take
an argument: the python executable with which to byte-compile .py files in the
package payload.

In some older versions of rpm (e.g. in RHEL 6), this invocation doesn't pass
in an argument, and brp-python-bytecompile defaults to using /usr/bin/python,
which can lead to the .py files being byte-compiled for the wrong version of
python.  This has been fixed in later versions of rpm by passing in
%{__python} as an argument to brp-python-bytecompile.

Workaround this by detecting if __os_install_post has a 0-argument invocation
of brp-python-bytecompile, and if so generating an equivalent macro that has
the argument, and explicitly provide the new definition within the specfile.
