    make python patch sane
    
    key differences:
    - actually works
    - don't search libpython in random locations (never invoke FindLibrary
      with bSimple=true)
    - use fixed PYTHON_LIBDIR defined in spec
    - don't descend into subdirectories
    - don't require library to end with _both_ .so and .dylib
      (filename.compare(filename.length() - 3, 3, ".so") == 0 &&
       filename.compare(filename.length() - 6, 6, ".dylib") == 0)
    - don't require devel symlink (*.so) to be present

-Subject: [PATCH] Follow PEP-384 when finding and opening python3 library
-
-Instead of maintaining a list of all Python versions the Python 3
-standard defines that there MUST be a stable ABI and we can always
-rely on a "python3.dll" or a "libpython3.so" existing.
-
-This also fixes library loading on Linux distributions that use
-SO versioned libraries.
