structures and functions used by the BFD generic linker, in case

any of the more specific linkers want to use or call them. Note

that some functions, such as _bfd_generic_link_hash_table_create,

are declared in libbfd.h, because they are expected to be widely

used. The functions and structures in this file will probably only
