* sysdeps/m68k/setjmp.c: Also define setjmp and _setjmp if

Browse Source 
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.
