gcc_4.5.1: add DSO linking change patch 

This patch changes gcc's (ld's) linking behavior. It passes
--no-add-needed flag to ld. Because of it ld does not try to find
related libraries for linking, causing link failures. And these
link failures can be fixed by specifying the library to be linked
explicitely on the gcc command line.
