varasm.c: Don't inlcude dbxout.h, sdbout.h or xcoffout.h.

	* varasm.c: Don't inlcude dbxout.h, sdbout.h or xcoffout.h.
	(asm_out_file): Remove redundant declaration.
	(assemble_asm): Remove old #if 0 block.
	(assemble_variable): Remove end of function; debug output is
	now handled with global_decl.  Remove old #if 0 block.  Update.
	Remove saved_in_section and associated no-op code.
	* Makefile.in (varasm.o): Correct dependencies.
