syscall_get_arch() is required to be implemented on all architectures
that use tracehook_report_syscall_entry() in order to extend
the generic ptrace API with PTRACE_GET_SYSCALL_INFO request.

v2: apparently, this architecture can be configured as big-endian,
so changed AUDIT_ARCH_NDS32 to be little-endian, and added
AUDIT_ARCH_NDS32BE.
