[PATCH] tile: default to tilegx_defconfig for ARCH=tile

[Chris Metcalf <cmetcalf@tilera.com>]

There is no "ARCH=tile" (just like there is no "ARCH=x86") so we need
to pick a default configuration, either tilepro or tilegx, when users
specify ARCH=tile.  We'll use tilegx, since that's our current chip.
