Subject: [PATCH 3.2 30/87] perf tools: Fix getrusage() related build
 failure on glibc trunk

3.2.53-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Markus Trippelsdorf <markus@...ppelsdorf.de>

commit 7b78f13603c6fcb64e020a0bbe31a651ea2b657b upstream.

On a system running glibc trunk perf doesn't build:

    CC builtin-sched.o
builtin-sched.c: In function ‘get_cpu_usage_nsec_parent’: builtin-sched.c:399:16: error: storage size of ‘ru’ isn’t known builtin-sched.c:403:2: error: implicit declaration of function ‘getrusage’ [-Werror=implicit-function-declaration]
    [...]

Fix it by including sys/resource.h.
