elf-em.h: add EM_CSKY

ldv-alt · guoren83 · commit 077b930adafe · 2018-12-30T21:14:07.000+08:00
The uapi/linux/audit.h header is going to use EM_CSKY in order
to define AUDIT_ARCH_CSKY which is needed to implement
syscall_get_arch() which in turn is required to extend
the generic ptrace API with PTRACE_GET_SYSCALL_INFO request.

The value for EM_CSKY has been taken from arch/csky/include/asm/elf.h
and confirmed by binutils:include/elf/common.h
