  Two small fixes for the support for SDKs on MacOSX:

  1) The code that checks if an path should be located in the SDK
     explicitly excludes /usr/local. This fixes issue9046

  2) The SDK variant for filtering "db_dirs_to_check" in setup.py
     was not doing anything because of a missing assignment.
