.S into the source file list, for reasons unknown, gcc only builds a .o
with the .S symbols/code in it; all the .c bits disappear.
So, a few changes:
1. add a rule for secondary.o, we're going to need it.
I like the fact that adding a .S file is inconvenient. Good.
Adding assembly should be hard.
2. Make two steps to initram .o building: first, the .c files, then any
extra .o files as specified by the mainboard Makefile
I realize this is a bit ugly, if there is a better solution, I'll take it.

That means if it ever gets called while CAR is active, our stack will be
dropped and mayhem will ensue.
Besides that, it just replicated stage0.S functionality which already
nukes all MTRRs before enabling CAR.
We could move XIP ROM caching from stage0.S to early_mtrr_init(). It
would probably slow down booting a bit, but the amount of asm code would
be reduced.
Thanks to Corey for telling me that early_mtrr_init() broke booting for
him.

This is a complete rewrite of my earlier stack checker proposal.
It works for CAR and RAM, has better abstraction and actually gives us
nice results.
The stack checker is default off due to its rather measurable impact on
boot speed.
Diagnostic messages are printed on first initialization, directly after
RAM init and directly before passing control to the payload. Sample qemu
log is attached. Extract from that log follows:

workarounds are better than instant reboots, mangle the code so that it
only switches stacks and flushes the cache.
There are two genuine fix in there as well:
We have to switch %esp before CAR is disabled. That way, the stack is
always valid.
And one of the nastier bugs easily happening in C: We had a pointer to a
const struct, but we wanted a const pointer to a struct. This kills the
(correct) warning about that code.
Many thanks to Corey for testing countless iterations of that code.
