This fails in several distros, among them centos:7, debian:8

CC /tmp/build/perf/util/header.o
util/header.c: In function '__event_process_build_id':
util/header.c:1473:11: error: missing initializer for field 'name' of 'struct kmod_path' [-Werror=missing-field-initializers]
struct kmod_path m = {};

centos:5, centos:6, debian:7 have a slightly different message:

CC /tmp/build/perf/util/callchain.o
cc1: warnings being treated as errors
util/header.c: In function '__event_process_build_id':
util/header.c:1473: warning: missing initializer
util/header.c:1473: warning: (near initialization for 'm.name')
MKDIR /tmp/build/perf/util/
CC /tmp/build/perf/util/values.o
mv: cannot stat `/tmp/build/perf/util/.header.o.tmp': No such file or directory


I'll fix this.
