Description

Currently, Scala builds from makefile require all build flags to be inherited from the Engine build. It should be as simple as linking libmxnet.so and libmxnet.a since these two files are already embedded with all dependencies required.

• first define why we are missing use_blas flag (and other flags) during build of .so file from JNI
• second identify what is necessary in order to build .so file for Scala package using the same flags as were used for original .so file of MXNet. It could be just copying flags config and preserve building .so file for Scala package, or it could be stop building .so file for Scala package code and use original .so file of MXNet as the only .so file in the package.
