* 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.
