That's quite an unusual path for NDK, but besides that is a too old version.

If you installed with Android studio, then th path should be
<sdk-directory>/ndk/<versionofndk>
(when using the new ndk option that allows you to install multiple
ndks, previously it would have been <sdk-directory>/ndk-bundle

Double-check the path you specified in your autogen.input. To mee it
looks like you omitted the Sdk directory.
While of course possible that it is indeed the path your ndk was
installed to, it would not be default settings...
