Android NDK tries to build with sdk/ndk-bundle/sources/cxx-stl/gnu-libstdc++/ but gnu-libstdc++ doesn't exist

I'm trying to build an old Android project which has native components.

When I try to build the project I get the following error:

Task :app:externalNativeBuildDebug FAILED
Build myappNative x86
[1/1] Linking CXX shared library ../../../../build/intermediates/cmake/debug/obj/x86/libmyappNative.so

ninja: build stopped: subcommand failed.

Which is pretty obvious:

error: no such file or directory: '/Users/Can/Library/Android/sdk/ndk-bundle/sources/cxx-stl/gnu-libstdc++/4.9/libs/x86/libgnustl_static.a'

When I go to /Users/Can/Library/Android/sdk/ndk-bundle/sources/cxx-stl/ there are only the following:

There is no such gnu-libstdc++ directory. What am I doing wrong?

UPDATE: For the meantime, I've switched back to old NDK r17c upon Alex Cohn's suggestion. It works, though that NDK is obsolete and this is just a temporary workaround, not a long term solution.

The following commands can be used to install the missing packages in linux based systems.

sudo apt-get update
sudo apt-get install libstdc++6

Since that project was released, NDK has dropped gnustl. You can still download NDK r.17 or earlier, or you can change your project to use libc++_static instead.
