 Review comment:
   we usually give these default build options for user to use while building from source. Should we have a section describing different build options from here - https://github.com/apache/incubator-mxnet/blob/master/make/config.mk explaining what each of those do so that the user can make an informed personalized choice for himself? Provide the default options, but also add this section. Thoughts?
