  1. Hide non-public symbols with LD version script 

    Version scripts provides information that can be used by GNU/Linux
distribution packaging tools. For example, Debian has a tool
dpkg-shlibdeps that can determine the minimal required version of each
dependency (by looking at the symbol list) and stuff the information
into the Debian specific packaging files.

We can utilize such feasture to reduce the size of shared library as
well.
