Add support for the OpenRISC 1000 platform
* configure.ac: Added or1k architecture..
* defs.h: Added or1k to use register reading system.
* linux/or1k/ioctlent.h.in: Use i386 ioctls.
* linux/or1k/syscallent.h: New file.
* process.c: Added or1k register defs to struct_user_offsets[].
* syscall.c: Added or1k_io iovec for or1k GETREGSET,
regset structure for or1k.
(printcall): Added handling for or1k.
(get_regs): Likewise.
(get_scno): Likewise.
(get_syscall_args): Likewise.
(get_syscall_result): Likewise.
(get_error): Likewise.
* util.c (change_syscall): Added dummy handling for or1k.
* system.c (sys_or1k_atomic): New function (or1k specific syscall).
