[Tracker] Libtool Library Versioning

[Martyn Russell <martyn imendio com>]

Hi all,

I have recently added libtool library versioning to libraries which are 
not loaded as modules - for the most part this is just src/lib*.

I have included the patch here.

Michael, can you comment if this is not adequate?
