Subject: [PATCH 1/3] perf tools: Fix a compiling error in trace-event-perl.c for 32 bits machine

On my x86_32 mahcine, there is a compile error:

	CC util/scripting-engines/trace-event-perl.o
	cc1: warnings being treated as errors
	util/scripting-engines/trace-event-perl.c: In function ‘perl_process_tracepoint’:
	util/scripting-engines/trace-event-perl.c:285: error: format ‘%d’ expects type ‘int’, but argument 2 has type ‘__u64’
	make: *** [util/scripting-engines/trace-event-perl.o] Error 1

Fix it by using the "%PRIu64" for __u64.

v2: use PRIu64 as suggested by Arnaldo.
