You are right:

  search_path = getenv ("PKG_CONFIG_PATH");
  if (search_path)
    {
      add_search_dirs(search_path, G_SEARCHPATH_SEPARATOR_S);
    }

  add_search_dirs(PKG_CONFIG_PC_PATH, G_SEARCHPATH_SEPARATOR_S);

PKG_CONFIG_PC_PATH is defined at build time so we need to remove the
PKG_CONFIG_PC_PATH from add_search_dirs().
