Compile Hostboot with -Os

Hostboot currently spends a significant percentage of
time loading data from PNOR across a relatively slow LPC
bus.  This commit enables compilation of Hostboot with
-Os, optimized for space to reduce the amount of data required
to be transferred across the LPC bus

Rough measurements show a ~30% size reduction of the hostboot
image and a ~10% reduction (improvement) in boot time
