[PATCH] (5/5) Enable Summit in makefile, update summit subarch code

["Martin J. Bligh" <mbligh@aracnet.com>]

Adds the summit subarch hook to the config file, and updates various things
all inside the summit subarch directories (ie this can't possibly break 
anyone else ;-)). The Summit's subarch had got out of sync in a few places.
