When more than one makefile tries to copy a header to the same destination, the warning is not clear, and hard to track down and assign blame: build/core/copy_headers.mk:15: warning: ignoring old commands for target `out/target/product/bullhead/obj/include/qcom/display/copybit.h' With this change, the same behavior is kept, but the warning message is more descriptive, and contains the offending Android.mk files: build/core/Makefile:54: Duplicate header copy: out/target/product/bullhead/obj/include/qcom/display/copybit.h build/core/Makefile:54: Defined in: hardware/qcom/display/msm8994/libcopybit/Android.mk hardware/qcom/display/msm8994/libcopybit/Android.mk In this case, a $(CLEAR_VARS) is missing, so the same Android.mk file is copying the same headers twice.
