Bug#175353: Many are architecture independent

thanks

Many (if not most) libraries have the same ABI on every architecture.
Examples:

>From gcc-3.2-3.2.3ds9:
        cp -p $(srcdir)/libstdc++-v3/config/linker-map.gnu \
                $(d_pic)/$(gcc_lib_dir)/libstdc++_pic.map
        (file is created during debian/rules unpack)
