Description: Use local object inventory files for sphinx
 Use the local object inventory files to prevent sphinx-build from 
 downloading them during build.
 This patch makes the intersphinx mappings depend on the existence of 
 these files, thus passing Debian Policy 12.3 while still maintaining 
 a level of comfort for the reader of the documentation.
