Commit 531d2410635c ("perf tools: Do not include stringify.h from the
kernel sources") seems to have accidentially removed the inclusion of
"util/header.h" from "arch/powerpc/util/header.c".
"util/header.h" provides the prototype for get_cpuid() and is needed to
build perf on Powerpc:
arch/powerpc/util/header.c:17:1: error: no previous prototype for 'get_cpuid' [-Werror=missing-prototypes]

randconfig builds can sometimes disable CONFIG_CPU_SUP_INTEL while
enabling the AMD power reporting PMU driver, resulting in this
build failure:
arch/x86/kernel/cpu/perf_event.h:663:31: error: 'events_sysfs_show' undeclared here (not in a function)
To fix it, move events_sysfs_show() outside of #ifdef CONFIG_CPU_SUP_INTEL.

A change on kernel files included by the 'perf bench memcpy' code grew some new
include deps, breaking the detached tarball build:
$ make -C tools/perf build-test

Add arch/*/include/asm/*features.h to tools/perf/MANIFEST so that we can
continue to use detached tarballs to build perf.
Now it builds ok, doing it manually:
$ make help | grep perf

So we need to trow away just stdout, leaving stderr to be caught by
the build tests infrastructure, so that we can see what went wrong
when the tarpkg build test fails:
$ make -C tools/perf build-test
make: Entering directory '/home/acme/git/linux/tools/perf'
- tarpkg: ./tests/perf-targz-src-pkg .
tests/make:302: recipe for target 'tarpkg' failed
make[1]: *** [tarpkg] Error 2
Makefile:102: recipe for target 'build-test' failed
make: *** [build-test] Error 2
make: Leaving directory '/home/acme/git/linux/tools/perf'
$ cat tools/perf/tarpkg
./tests/perf-targz-src-pkg .
PERF_VERSION = 4.5.g05f5ec
PERF_VERSION = 4.5.g05f5ec
In file included from bench/mem-memcpy-x86-64-asm.S:9:0:
bench/../../../arch/x86/lib/memcpy_64.S:5:29: fatal error: asm/cpufeatures.h: No such file or directory
compilation terminated.
mv: cannot stat ‘bench/.mem-memcpy-x86-64-asm.o.tmp’: No such file or directory
make[5]: *** [bench/mem-memcpy-x86-64-asm.o] Error 1

make[2]: *** [all] Error 2
$
So the test flow is:
1. Run: 'make -C tools/perf build-test'
2. One of its tests failed, in this case, the 'tarpkg' one
3. Look at what went wrong, by looking at the output of that test, in
tools/perf/tarpkg
Admittedly, this should be shortcircuited to showing what went wrong directly
from the 'make build-test' step, but lets first fix this tarpkg one and the
problem it spotted, which should be fixed by adding some extra file to the
tools/perf/MANIFEST so that detached tarballs continue being self contained and
build successfully.

variable length strings, use them.

That doesn't chekcs malloc return and that, when using strbuf, if it
can't grow, just explodes away via die().
