Subject: [PATCH] powerpc: include <asm/ptrace.h> for PT_NIP declaration

This patch conditionally includes <asm/ptrace.h> when available to
ensure PT_NIP is properly declared, fixing build failures such as:

  error: 'PT_NIP' was not declared in this scope; did you mean 'PT_NUM'?

It happened on musl and powerpc
