which: enable 64-bit API on 32-bit systems

Browse Source 
Without the change `which` fails to find programs on filesystems with
64-bit inodes when `which` itself is 32-bit.

In my case it is `btrfs` and `i686-linux`.

`bison` is in the PATH:

    $ dev>bison
    bison: missing operand
    Try 'bison --help' for more information.

But `which` fails to find it:

    $ which bison
    which: no bison in ...

`bison` is a file with an inode number that overflows 2^31 limit:

    $ stat ~/bin/bison
      File: ~/bin/bison
      Size: 674260          Blocks: 1320       IO Block: 4096   regular file
    Device: 0,29    Inode: 4384368825  Links: 2
    Access: (0555/-r-xr-xr-x)  Uid: (    0/    root)   Gid: (    0/    root)

The change fixes `which` run.
