* ecoff.c (ecoff_frob_symbol): New function. Put undefined

	symbols of known size in the undefined section.  Put small common
	symbols in a .scommon section.
	* ecoff.h (ecoff_frob_symbol): Declare.
	* config/obj-ecoff.h (obj_frob_symbol): Define.
	* config/obj-elf.c (obj_elf_write_symbol_p, obj_elf_write_symbol,
	obj_elf_frob_symbol): Removed unused functions.
	* config/obj-elf.h (obj_frob_symbol, obj_write_symbol): Removed
	unused macros.
	(obj_elf_frob_symbol, obj_elf_write_symbol): Removed declarations
	of unused functions.
	(obj_frob_symbol): Define if ECOFF_DEBUGGING.
