* ldlnk960.c: Use new naming convention for *.x{,u,r} include scripts.

* ldm88k.sc: "Clean up" script, so that ldm88kUr.sc and ldm88kr.sc
	can be automatically generated.
	* ldemul.c, configure.in, config.h, Makefile.in:
	Add support for Sony NewsOS3.
	* Makefile.in: Re-do the way ldemulation scipts and structures
	are done. do we only need one or two files for each emulation
	target (a TARGET.sc and optionally TARGET.c, if ldtemplate
	isn't suitable).  This gets rid of lots of extra source files.
