      Document known issue with ND4J libraries and CPU AVX/AVX2 support.

      Known issue:
      libnd4j binary was built with AVX/AVX2 support, but current CPU doesn't have this instruction set. Exiting now...

      Check to be sure your processor has at least AVX support. For example, the Intel Xeon E5-2690 does have AVX support but not AVX2.

      Solution
      Exclude AVX2 libs:

      <dependency>
  <groupId>org.nd4j</groupId>
  <artifactId>nd4j-native</artifactId>
  <version>${dl4jVersion}</version>
  <classifier>linux-x86_64-avx2</classifier>
</dependency>
<dependency>
  <groupId>org.nd4j</groupId>
  <artifactId>nd4j-native</artifactId>
  <version>${dl4jVersion}</version>
  <classifier>macosx-x86_64-avx2</classifier>
</dependency>
<dependency>
  <groupId>org.nd4j</groupId>
  <artifactId>nd4j-native</artifactId>
  <version>${dl4jVersion}</version>
  <classifier>windows-x86_64-avx2</classifier>

  <groupId>org.nd4j</groupId>
  <artifactId>nd4j-native</artifactId>
  <version>${dl4jVersion}</version>
  <classifier>linux-ppc64le-avx2</classifier>
