a5ccdad1fc * elfcode.h (elf_object_p): Rather than looking through an array
of architectures, get the ELF EM_xxx code from the backend

32090b8e4f * elf.c, elfcode.h, libelf.h: Serious reorganization.
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
bfd_perform_relocation lossage.

	* libelf.h (struct elf_obj_tdata and associated macros): Moved
	here from elfcode.h.  A couple of size-specific structure pointers
	were changed to PTR; uses fixed appropriately.

	(bfd_elf_mkobject): Renamed from bfd_elf32_mkobject.
	(bfd_elf32_mkobject, bfd_elf64_mkobject, elf_mkobject): New

	from elfcode.h.
