Fails in some environments, such as debian:experimental-x-mipsel:
CC /tmp/build/perf/util/evlist.o
util/event.c: In function 'perf_event__fprintf_namespaces':
util/event.c:1129:33: error: format '%lu' expects argument of type 'long
unsigned int', but argument 5 has type 'long long unsigned int'
[-Werror=format=]
ret += fprintf(fp, "%u/%s: %lu/0x%lx%s", idx,
^
util/event.c:1129:39: error: format '%lx' expects argument of type 'long
unsigned int', but argument 6 has type 'long long unsigned int'
[-Werror=format=]
ret += fprintf(fp, "%u/%s: %lu/0x%lx%s", idx,
^
CC /tmp/build/perf/builtin-list.o

Fixing this up to use PRIu64...
