Linker fixes for multiple weak symbols.

    We have issues with weak symbols containing member variables
    if they exist in multiple modules because each module's code
    ends up with their own copy.  For objects like Singleton's
    this is bad because the objects are no longer singleton.

    The original solution for this was to prohibit multiple
    definition of the same weak symbol.  This causes extra errors
    when using templated code such as using a vector<foo> in two
    different modules.

    The solution here is to search for member values inside of a
    weak symbol instead of just duplicate weak symbols.  This
    allows multiple weak symbol definitions as long as those
    weak symbols do not have a contained member value (like a
    singleton instance would).
