The value of CFG_TEE_TA_LOG_LEVEL used at optee_os build time is
exported to the TA dev kit ($O/export_ta_arm{32,64}/mk/conf.mk). The
purpose is to provide a default value to the TA build environment,
which can easily be changed from the command line ("make
CFG_TEE_TA_LOG_LEVEL=3" for example).
However the following TA Makefile won't behave as expected:
BINARY := <somme uuid>
CFG_TEE_TA_LOG_LEVEL := 3 # Ignored!
include $(TA_DEV_KIT_DIR)/mk/ta_dev_kit.mk
This commit changes := to ?= so that ta_dev_kit.mk won't override any
value that may have been set previously in the TA Makefile or the
environment.
