[PATCH 2/4] build: Alloc space for sched list in the link file

[Jonathan Creekmore <jonathan.creekmore@gmail.com>]

Creates a section to contain scheduler entry pointers that are gathered
together into an array. This will allow, in a follow-on patch, scheduler
entries to be automatically gathered together into the array for
automatic parsing.
