perf build: Do not use -Wshadow on gcc < 4.8 (2019-07-23 09:04:54 -0300)

----------------------------------------------------------------
perf/urgent fixes:

perf.data:

Alexey Budankov:

- Fix loading of compressed data split across adjacent records

Jiri Olsa:

- Fix buffer size setting for processing CPU topology perf.data header.

perf stat:

Jiri Olsa:

- Fix segfault for event group in repeat mode

Cong Wang:

- Always separate "stalled cycles per insn" line, it was being appended to
the "instructions" line.

perf script:

Andi Kleen:

- Fix --max-blocks man page description.

- Improve man page description of metrics.

- Fix off by one in brstackinsn IPC computation.

perf probe:

Arnaldo Carvalho de Melo:

- Avoid calling freeing routine multiple times for same pointer.

perf build:

- Do not use -Wshadow on gcc < 4.8, avoiding too strict warnings
treated as errors, breaking the build.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

The 'perf test bpf' test is about rlimit(MEMLOCK), bump it a to 128K from the
default 64K and it'll work. Next pull req will have auto-adjustment for 'perf
test' and 'perf trace', where BPF programs creating maps are also failing.

This is with the following patches that are via thru the BPF tree:

89bf23d6a1da libbpf: Avoid designated initializers for unnamed union members
df538f1f4574 libbpf: Fix endianness macro usage for some compilers
c8911bbb835a libbpf: Fix missing __WORDSIZE definition

And this one that was already in the BPF tree:

3925b9a45f6d libbpf: fix ptr to u64 conversion warning on 32-bit platforms
