* coff-mips.c (ecoff_set_symbol_info): stBlock symbols are always

debugging symbols.
	(ecoff_get_debug): Offset the fdr adr by the adr of the first pdr,
	for compatibility with tools from MIPS.

	* config/bigmips.mt: New file; default vector is ecoff_big_vec.
	* config/irix3.mt, config/irix4.mt: Removed.
	* configure.in (mips-*-ecoff): New target; uses bigmips.mt.
	(mips-sgi-*, mips-big-*): Use bigmips rather than irix3.

* hosts/hp300bsd.h: Add gross hack to determine whether we
are running on BSD 4.3 or BSD 4.4, and use appropriate include
files (and set other parameters) to match.
