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
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

$
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
perf-tar-src-pkg - Build perf-4.5.0.tar source tarball
perf-targz-src-pkg - Build perf-4.5.0.tar.gz source tarball
perf-tarbz2-src-pkg - Build perf-4.5.0.tar.bz2 source tarball
perf-tarxz-src-pkg - Build perf-4.5.0.tar.xz source tarball
$ ls -la perf-4.5.0.tar
ls: cannot access perf-4.5.0.tar: No such file or directory
$ make perf-tar-src-pkg
