Subject[PATCH 15/13] unicore32: define syscall_get_arch()
syscall_get_arch() is required to be implemented on all architectures
in order to extend the generic ptrace API with PTRACE_GET_SYSCALL_INFO
request.

Signed-off-by: Dmitry V. Levin <ldv@altlinux.org>

Apparently, we need to implement syscall_get_arch() on all architectures
where linux/tracehook.h is compiled, not just those that use
tracehook_report_syscall_entry().
This adds one more architecture to the initial list of 9 architectures
where syscall_get_arch() has to be implemented.
