Dave, I'm afraid I can confuse you again.
So, as Tony pointed out, both utrace-3.0 and utrace-3.1 need
this fix, to fix the build on !x86 platform.
This is for utrace-3.0, I'll send the same patch in reply to
"[PATCH 0/31] utrace for 3.1 kernel".
Or should I do something else?

TIF_SYSCALL_EMU is x86 only, add ifdef into ptrace_report_syscall().
