I will propose in other thread to have a specific CONFIG to compile the the OP-TEE library

CONFIG_OPTEE => CONFIG_OPTEE_LIB

CONFIG_OPTEE will be kept only to manage the OP-TEE driver compilation
(depending TEE uclass / CONFIG_TEE)

but if you need to have the LIBRARY available in SPL
(to avoid to increase the SPL size of other board)

I think the configuraiton CONFIG_SPL_OPTEE_LIB should be added
then the Makefile becomes
  
+obj-$(CONFIG_$(SPL_)OPTEE) += optee/
