There is a way to do this. (Although, it might not do exactly what you want.)
You need to do two links, the first one with -r, linking all your files 
together. Then run strip --strip-unneeded on the resulting file. After 
that, you can link that object file with your libraries.
  What this will do is link all your .o files together into one, and remove
all the resolved symbols. Then, when you link with the libraries, your 
function f(..) will already have been resolved, and it's name removed 
from the symbol table. The bad thing about this method is that it makes 
debugging harder...  Also, there would then be no way to call function 
f(..) from the library.

But I hope this helps.
