Yes, debug relocations will contribute to link time.  So will the mere
fact that the linker needs to copy more data around.  However, the
biggest time consumer is the optimisation.  Particularly with older
linkers, the string merging process takes a lot of time.  (Debug info
tends to have a lot of strings.)
