..................................

   Before the linker calls the `_bfd_final_link' entry point, it sets
up some data structures for the function to use.

   The `input_bfds' field of the `bfd_link_info' structure will point
to a list of all the input files included in the link.  These files are
linked through the `link_next' field of the `bfd' structure.

   Each section in the output file will have a list of `link_order'
structures attached to the `link_order_head' field (the `link_order'
structure is defined in `bfdlink.h').  These structures describe how to
create the contents of the output section in terms of the contents of
various input sections, fill constants, and, eventually, other types of
information.  They also describe relocs that must be created by the BFD
backend, but do not correspond to any input file; this is used to
support -Ur, which builds constructors while generating a relocateable
object file.
