.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.
