[PATCH] perf, tools: Make build fail on JSON parse error

[Andi Kleen <andi@firstfloor.org>]

From: Andi Kleen <ak@linux.intel.com>

Today, when a JSON file fails parsing the build continues,
but there are no json files built in, which is difficult to debug later.
Make the build stop on a parse error instead.
