> We have been using gcc 4.8.5 to Singa.
> The latest gcc is 8.2. Many dependent libs (e.g., protobuf) are built with newer versions
of gcc which has a different ABI as 4.8.5.
> This ticket is going to update these libs and gcc using [conda-build 3.0|[https://www.anaconda.com/package-better-conda-build-3/].]
>  # introduce the build, host and run sections in meta.yaml
>  # introduce the conda_build_config.yaml to configure the lib versions. note the gcc
version [must be 5.4|https://docs.conda.io/projects/conda-build/en/latest/resources/variants.html]
as cuda does not support gcc>=6.
>  # use the compiler selected by conda via c_complier() cxx_compiler()
>  # use the cudnn from anaconda.
>  # move docker for conda build into tool/conda. Now the dockerfile for conda build and
the dockerfile for devel are different. The former one uses the libs from anaconda. The later
one uses the latest libs from ubuntu.
