[svn-r13475] There's a configure issue linking szip's shared libraries when running on kagiso.

The static szip libraries are working as intended, but when shared szip 
libraries are present and intended for use they cannot be opened. A check 
has been implemented to test if shared szip libraries are functional on 
current platform. If they are not, and the user is trying to use them, 
szip is now disbaled and the user is informed.

This issue occurs on kagiso, and the resolution was tested on kagiso.
