Brian mentioned displaying relocs alongside the disassembly, which will 
help you with object files, but I suspect will not provide you with all 
of the information you are hoping to see.

In essence though the answer is "no", because it is just too difficult 
to recognise all references to global variables or functions.  A global 
variable might be accessed directly or via a base address plus an 
offset, or loaded into one register and then copied into another 
register, or aliased via a union or type punning.  Functions can have 
multiple entry points, or can be overlayed or even dynamically 
constructed at run-time.
