perf annotate on a ppc64 build (no TUI) is failing. I get zero output.
I haven't had a chance to look closer, but I used the following git
bisect test script to isolate:


#!/bin/sh

cd tools/perf

make || exit 125

PERF=./perf

$PERF record -a sleep 5

if [ -z "`$PERF annotate`" ]; then
	exit 1
else
	exit 0
fi
