Atari support, from Uwe Seimet (seimet@chemie.uni-kl.de).
* configure.in (m68*-atari-sysv4*): New configuration.
(m68*-cbm-sysv4*): Use m68kv4 instead of amix.
* m68k-tdep.c (R_PS): Define as R_SR if necessary.
* config/m68k/m68kv4.mh, config/m68k/m68kv4.mt,
config/m68k/tm-m68kv4.h, config/m68k/xm-m68kv4.h: New files.
* config/m68k/amix.mh, config/m68k/amix.mt,
config/m68k/tm-amix.h, config/m68k/xm-amix.h: Removed, superseded
by m68kv4 files.
