autoconf: add "tile" to config.sub for Tilera's chip

[Chris Metcalf]

Tilera recently announced itself as a company (www.tilera.com) and is 
selling its first chip, the Tile64.  We've developed our toolchain 
around binutils, and are using Linux as our OS (64-way SMP!) so we'd 
like to start getting the "tile" name recognized by configure so it's 
easier for people to start porting stuff to our platform over time.

Thanks!
