nk-example build fails on Ubuntu

[wilyarti]

I have installed the NDK and have my variables set. The make command fails with the following:

I have no got it to compile using gradle and a custom build script.

[wilyarti]

The failure to compile is due to gcc. Changing the Makefile to use clang fixes this problem.

However ant is deprecated. I used gradlew to build and install the project.
