Android makefile looking for clang++ in wrong folder

When I compile the Android examples I get the following error:
E:/Android/NDK/android-ndk-r12b//toolchains/llvm-3.6/prebuilt/windows/bin/clang++: No such file or directory

The makefile (openFrameworks\libs\openFrameworksCompiled\project\android\config.android.default.mk) appears to be appending the LLVM version number to the toolchain folder:
TOOLCHAIN=llvm-$(CLANG_VERSION)

But the NDK(android-ndk-r12b-windows-x86_64) doesn’t install clang++ there, it goes in:
E:/Android/NDK/android-ndk-r12b//toolchains/llvm/prebuilt/windows/bin/clang++

Is this just a bug in the makefile for windows? Or am I missing a step?

Full gradle/make output below
