Add basic VNDK support in Make Add BOARD_VNDK_VERSION and LOCAL_USE_VNDK to specify the version of the VNDK that will be used globally, and whether to use the VNDK on a module basis. If the board is using the VNDK: * LOCAL_COPY_HEADERS may only be used by modules defining LOCAL_USE_VNDK * LOCAL_USE_VNDK modules will compile against the NDK headers and stub libraries, but continue to use the platform libc++. * LOCAL_USE_VNDK modules will not have the global includes like system/core/include, but it will use device-specific kernel headers. This change does not attempt to enforce any linking constraints, that will come in a later patch.

Stop removing valid copy headers My change to clean up obsolete copy headers would remove valid ones if thhe LOCAL_COPY_HEADERS_TO path wasn't cleaned. I'm seeing this most with values that just end in '/', so we end up with a '//' in the path, which isn't textually equivalent, and we remove it.

Warn more clearly when there are duplicate copied headers 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.
