[Q] Error trying to compile 4.2 for toro

Hi all I am attempting to compile 4.2 for toro and ran into an issue. I synced my repo, got the new binaries, setup up build enironment, did lunch and choose option 13 (full_toro_userdebug), enter the command "make -j4 otapackage" and when it gets to checking build tools version I get the following error message

"build/core/binary.mk:11: *** external/bzip2: LOCAL_NDK_VERSION is now retired.. Stop"

Does anyone know how to resolve this? Any help will be greatly appreciated.
