[PATCH 09/14] nds32: define syscall_get_arch()

[Dmitry V. Levin]

syscall_get_arch() is required to be implemented on all architectures
in addition to already implemented syscall_get_nr(),
syscall_get_arguments(), syscall_get_error(), and
syscall_get_return_value() functions in order to extend the generic
ptrace API with PTRACE_GET_SYSCALL_INFO request.

 This is just a gentle ping, the patch is unchanged.
