* libelf.h (struct Elf_Sym_Extra): New structure to contain ELF
specific information for a symbol. Put in elf_sym_num, which
gives the external symbol number in the elf object file, since
local symbols must come before global symbols.
(elf_sym_extra): New macro.
(elf_symtab_map): Delete, in favor of using Elf_Sym_Extra.
* elfcode.h (elf_map_symbols): Use Elf_Sym_Extra to map internal

* elfcode.h (elf_obj_tdata): Add pointer to an array of pointers

(elf_symbol_from_bfd_symbol): If udata is NULL, and this is a section symbol,
look up the section in the list of section symbols, and set the udata pointer
appropriately. Otherwise, if udata is still NULL, fail an assertion, and use

Tue Jun 15 14:38:32 1993 Michael Meissner (meissner@osf.org)

that is what is in elf.c.
Deleted `thunk' structure, merged into tdata, duplicate data eliminated.
Rearranged functions, grouping by function.
Broke up many functions in elfcode.h, re-ordered many parts of file writing
to handle unpredictable state of section relocation table as provided by
various applications.
Still needs cleanup: Merge functions back together, split out data structure
with only data that is used only when writing out object file.
* elf.c (bfd_elf_generic_reloc): New function, taken from coff-mips.c.
* elf32-sparc.c (elf_sparc_howto_table): Use it, to work around
