* subsegs.c (subseg_new): Set output_section of new section.

	* as.c (perform_an_assemly_pass): Don't set output_section here.
	* expr.c (expr_part, expr): Turn off section assertions for ECOFF,
	since it has additional sections.
	* read.c (s_lcomm): For MIPS ECOFF, put small objects in .sbss,
	not bss_section.
	* config/obj-ecoff.h (TARGET_SYMBOL_FIELDS): Added
	ecoff_undefined field.
	* config/obj-ecoff.c (obj_symbol_new_hook): Initialize
	ecoff_undefined field.
	(add_file): If using stabs, just output a stabs symbol rather than
	creating a new fdr.
	(obj_ecoff_begin, obj_ecoff_bend): Ignore line number by reading
	it with get_absolute_expression, rather than skipping it by hand.
	(obj_ecoff_loc): If using stabs, just output a stabs symbol rather
	than ECOFF line number information.
	(obj_ecoff_stab): Accept non-zero values for stabs line number.
	(ecoff_build_symbols): Set ifilesym correctly.  Set storage class
	to small, undefined and/or readonly sections if appropriate.
	Don't output symbol names containing \001 characters.
	(ecoff_frob_file): Make sure at least one fdr is output.
	* config/tc-mips.h: Define TC_MIPS.
	* config/tc-mips.c (g_switch_value): New static variable.
	(md_assemble): Set gp size of output BFD.
	(gp_reference): New function; returns 1 if expression can be
	accesssed via gp.  Always returns 0 if not using ECOFF.
	(macro_build): Convert BFD_RELOC_LO16 to BFD_RELOC_MIPS_GPREL if
	possible.
	(macro): Generate sequences using gp if possible.
	(md_parse_option): Ignore -EL and -EB.  Parse -G.
	(md_apply_fix): Added BFD_RELOC_MIPS_GPREL to ignored case.
	(s_change_sec): Handle .rdata and .sdata for ECOFF.
	(s_extern): Mark symbol as external.  Set ecoff_undefined field.
