You neglected to mention what type of debugging information you are
using, or even what type of system you are using.

The linker is able to eliminate most duplicate COFF debugging
information and almost all duplicate stabs debugging information.  It
has not support for eliminating duplicate DWARF debugging information,
although I think that would be a very good idea.
