* configure.in: Add Lynx/rs6000 support.
* lynx-nat.c: Clean up some Sparc stuff. Clean up ptrace error messages. Add rs6000 support. Don't try to modify unwritable registers. * rs6000-nat.c: Move lots of native dependent stuff (like core file support) from rs6000-tdep.c & xcoffexec.c to here. * rs6000-tdep.c: Move native dependent stuff to nat.c. * xcoffexec.c: Move native dependent stuff to nat.c. * config/rs6000/nm-rs6000.h: Move defs of SOLIB_* macros to here from tm file. * config/rs6000/tm-rs6000.h: Remove defs of SOLIB_* funcs, cuz they're really native. * config/rs6000/tm-rs6000lynx.h, config/rs6000/xm-rs6000lynx.h: New files to support Lynx/rs6000.
