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)
