Change lldb from building against a Python framework out of
the installed SDK to using the current OS installed headers/libraries.
This change is to address the removal of the Python framework
from the Mac OS X 10.9 (Mavericks) SDK, and is the recommended
workaround via https://developer.apple.com/library/mac/technotes/tn2328/_index.html
