    If CONFIG_BTRFS_FS is y and CONFIG_LIBCRC32C is m,
    building fails:
      fs/btrfs/super.o: In function `btrfs_mount_root':
      super.c:(.text+0xb7f9): undefined reference to `crc32c_impl'
      fs/btrfs/super.o: In function `init_btrfs_fs':
      super.c:(.init.text+0x3465): undefined reference to `crc32c_impl'
      fs/btrfs/extent-tree.o: In function `hash_extent_data_ref':
      extent-tree.c:(.text+0xe60): undefined reference to `crc32c'

      fs/btrfs/dir-item.o: In function `btrfs_insert_dir_item':
      dir-item.c:(.text+0x429): undefined reference to `crc32c'
    Select LIBCRC32C to fix it.
