* sysdeps/m68k/setjmp.c: Also define setjmp and _setjmp if
BSD_SETJMP or BSD__SETJMP is defined, resp. * sysdeps/m68k/bsd-setjmp.c: Inline setjmp code instead of making a tail call to __sigsetjmp that would require extending the caller's frame. * sysdeps/m68k/bsd-_setjmp.c: Likewise. * sysdeps/m68k/bsd-setjmp.S: Deleted. * sysdeps/m68k/bsd-_setjmp.S: Deleted.
