Basically, for every subprogram, it links the individual object files of
that subprogram into subprogram.o with ld -r and then does some
post-processing of the symbol table. A library is not really an
alternative as it would be then required to figure out which symbols are
not used etc. All that complexity can be side stepped with ld -r.
