bss space instead of common.
(md_parse_option) [OBJ_ELF]: Print version id for -V. Ignore -Q and -s options

* m88k-opcode.h : fixed tiny tiny mistake - xcr was incorrectly
specified, should have both S1 and S2 fields identical
If only finding the problem was as fast as fixing the bug !!!!

ecoff_undefined field.

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.

dropping a space immediately following an identifier.
* expr.c, write.c: Rewrote assert expressions to not use multiple
lines; I don't think that can be done portably.
* config/tc-mips.c (macro): Use $AT if target register is zero in
load instruction, which it can be for a floating point load.
Also a bunch more changes to config/obj-ecoff.c, still in flux.
the section contents.
* config/obj-ecoff.h, config/obj-ecoff.c: Numerous changes to get
symbol table and values right.
* config/tc-mips.h (LOCAL_LABEL): If OBJ_ECOFF, any label starting
with $L is local.
* config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
by the section vma.
* config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
z8k-opc.h, not z8k.h.
* config/obj-ecoff.c, config/obj-ecoff.h: Preliminary ECOFF
support.

OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
(struct loc, struct proc, struct file): Moved to tc-mips.c within
#ifndef OBJ_ECOFF block, since ECOFF uses different versions.
* config/tc-mips.c: Rearranged for ECOFF support. Added
prototypes for all static functions. Moved existing minimal
debugging format support info #ifndef OBJ_ECOFF blocks.
(macro_build_lui): Eliminated sign_extend argument, because ECOFF
does not support a non sign extended high 16 bits reloc. Adjusted
all callers accordingly.
(tc_get_register): Renamed from get_register, and made non-static.
* config/mips-big.mt, config/mips-lit.mt: New files. Define
TARGET_BYTES_BIG_ENDIAN and TARGET_BYTES_LITTLE_ENDIAN,
respectively.

(mips-*-ultrix*, mips-*-irix*, mips-*-ecoff): New targets, using
obj_format ecoff and gas_target mips-lit or mips-big.
* config/obj-coffbfd.c (fill_section): Don't set vaddr here.
(write_object_file): Set it here instead, so that fixup_segment
can see the correct value.
