Issue #15184: Some config variables in test_sysconfig_module
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.
