Change 55144 by jmallett at jmallett_oingo on 2004/06/17 09:17:00

	Take a stab at doing tranditional MIPS support for n32 ABI, and
	add support for shared stuff to ld's n32 config.  Make AS use the
	N32 ABI.  Make LD generate and use the new N32 tradmips stuff.  Move
	BFD back to using ntradmips.  Slash and hack ldscript.  Untested.
