16.05 printf test does not build for Cortex A9.

[Bob Stewart]

Hi,

     It appears that the 16.05 build uses a new environment parameter 
BASE_HW_DIR, which cause a build on a Cortex A9 based platform to fail 
in lib/mk (that is, base-hw/lib/mk/spec/cortex_a9.h)

This can be fixed by including in cortex_a9.h the line;

BASE_HW_DIR := $(REP_DIR)

But why is it necessary to have this new variable?
