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.

different parsing of the Makefile by distutils.sysconfig and
sysconfig in the case when an intermediate config vars, used to
construct PY_CFLAGS or PY_LDFLAGS, has a trailing space character.
In this case, the OS X installer build script was leaving a
trailing space in the OPT and LDFLAGS config vars.  The space is not
significant and it's not worth toying with the Makefile parsing.

by removing unwarranted assumptions that clang compiler chain
cannot handle ppc (the driver passes off ppc compiles to gcc).
Mock the behavior instead.

This sentence appears as a clarifying note in the HTML docs, and seems
worth having in the docstring since it covers a very common use case
that isn't otherwise obvious.  Thanks to Yongzhi Pan for the suggestion.

build paths from configuration variables cached in _sysconfigdata.py, as
is already done for the installed Makefile.  This avoids a distuils test
case failure in test_ldshared_value.

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.

stringbench).

This should make the Linux distros happy as it is now easier to leave
importlib's tests out of their base Python distribution.

no difference anymore between __import__ and importlib.__import__.
