What ld man page says about -z defs:

            Report unresolved symbol references from regular object 
files.  This is done even if the linker is creating a non-symbolic 
shared library.  The switch --[no-]allow-shlib-undefined controls
            the behaviour for reporting unresolved references found in 
shared libraries being linked in.

So as far as I understand, the only effect of the option is to generate 
additional errors. How does it help you to remove the dependencies?
