[PATCH] Add support for Tilera TILE-Gx processor (part 1/2: gdb)

[Jeff Kenton <jkenton@tilera.com>]

This is a port of GDB to the Tilera TILE-Gx processor.

I broke this into 2 parts:  the first (this part) contains changes to
configure and Makefiles.  Changes are based on the gdb-7.4.50.20120410
snapshot.  The second part contains new Tilera specific files.


Comments please.

Thanks.
