As it is used by several other tools, better move it outside tools/perf.

To compile for little-endian systems, you need to pass -EL to CC and LD.
EXTRA_CFLAGS works to pass -EL to CC.
Add EXTRA_LDFLAGS to pass -EL to LD.

Set FEATURE_TESTS to 'all' so all possible feature checkers are
executed. Without this setting the output feature dump file miss some
feature, for example, liberity. Select all checker so we won't get an
incomplete feature dump file.

There's a bug in LLVM that it can generate unneeded relocation
information. See [1] and [2]. Libbpf should check the target section of
a relocation symbol.
This patch adds a testcase which references a global variable (BPF
doesn't support global variables). Before fixing libbpf, the new test
case can be loaded into kernel, the global variable acts like the first
map. It is incorrect.
Result:
# ~/perf test BPF

Makefile.perf:414: recipe for target 'libtraceevent_plugins' failed
make[1]: *** [libtraceevent_plugins] Error 2
make[1]: *** Waiting for unfinished jobs....
Currently we have the install-traceevent-plugins target being dependent
on $(LIBTRACEEVENT), which will actualy not build any plugin. So the
install-traceevent-plugins target itself will try to build plugins,
but..
Plugins built is also triggered by perf build itself via
libtraceevent_plugins target.
This might cause a race having one make thread removing temp files from
another and result in above error. Fixing this by having proper plugins
build dependency before installing plugins.

By adding libbpf into perf's Makefile, this patch enables perf to build
libbpf if libelf is found and neither NO_LIBELF nor NO_LIBBPF is set.
The newly introduced code is similar to how libapi and libtraceevent
are wired into Makefile.perf.
MANIFEST is also updated for 'make perf-*-src-pkg'.
Append make_no_libbpf to tools/perf/tests/make.
The 'bpf' feature check is appended into default FEATURE_TESTS and
FEATURE_DISPLAY, so perf will check the API version of bpf in
/path/to/kernel/include/uapi/linux/bpf.h. Which should not fail except
when we are trying to port this code to an old kernel.
Error messages are also updated to notify users about the lack of BPF
support in 'perf record' if libelf is missing or the BPF API check
failed.
tools/lib/bpf is added to TAG_FOLDERS to allow us to navigate libbpf
files when working on perf using tools/perf/tags.

Add support for decoding instructions for Intel Processor Trace. The
kernel x86 instruction decoder is copied for this.
This essentially provides intel_pt_get_insn() which takes a binary
buffer, uses the kernel's x86 instruction decoder to get details of the
instruction and then categorizes it for consumption by an Intel PT
decoder.

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
New features:
- Allow filtering out of perf's PID via 'perf record --exclude-perf'. (Wang Nan)
- 'perf trace' now supports syscall groups, like strace, i.e:
$ trace -e file touch file
Will expand 'file' into multiple, file related, syscalls. More work needed to
add extra groups for other syscall groups, and also to complement what was
added for the 'file' group, included as a proof of concept. (Arnaldo Carvalho de Melo)
- Add lock_pi stresser to 'perf bench futex', to test the kernel code
related to FUTEX_(UN)LOCK_PI. (Davidlohr Bueso)
User visible fixes:
- Apply --filter to all events in a glob matching, not just the last one. (Wang Nan)
Documentation changes:
- Document setting '-e pmu/period=N/' in the 'perf record' man page. (Kan Liang)
Infrastructure changes:
- 'perf probe' code simplifications and movements to separate files. (Masami Hiramatsu)
- Fix makefile generation under 'dash'. (Sergei Trofimovich)

Commit 5ef7bbb09f7b ("perf tools: Allow to specify custom linker
command") was meant to enable usage non $(CROSS_COMPILE)ld linker during
perf building.
But implementation didn't take into account the fact that LD is a
pre-defined variable in GNU Make. I.e. it is always defined.
Which means there's no point to check "LD ?= ..." because it will never
succeed.
And so LD will be either that explicitly passed to make like this:
------->8-------
make LD=path_to_my_ld ...
------->8-------
or default value, which is host's "ld".
Latter leads to failure of cross-linkage because instead of cross linker
"$(CROSS_COMPILE)ld" host's "ld" is used.
Fortunately there's a way to do correct substitution of $(CROSS_COMPILE)ld
with user defined LD on command-line.
As a reference was used implementation in "tools/lib/traceevent/Makefile".
Build tested for x86_64 and ARC.
Thanks Jiri for this hint.

Allow to specify custom linker command. This fixes MIPS64 builds for
64-bit userspace as it will allow to pass a linker using the correct
linker flags for 64-bit ABI (by default GNU binutils ld will assume

Commit e3d09ec8126fe2c9a3ade661e2126e215ca27a80 ("tools lib traceevent:
Export dynamic symbols used by traceevent plugins") adds libtraceevent
dynamic list directly into LDFLAGS, which makes all targets depend on
that list through LDFLAGS.
This is not good since some of targets like libgtk.so doesn't use plugin
at all, but require the existance of that list because of linker
options.
This patch isolates the -Xlink option into LIBTRACEEVENT_DYNAMIC_LIST_LDFLAGS,
makes only perf and perf.so use it.

This is caused by commit e3d09ec8126fe2c9a3ade661e2126e215ca27a80

Traceevent plugins need dynamic symbols exported from libtraceevent.a,
otherwise a dlopen error will occur during plugins loading.
This patch uses dynamic-list-file to export dynamic symbols which will
be used in plugins to perf executable.
The problem is covered up if feature-libpython is enabled, because
PYTHON_EMBED_LDOPTS contains '-Xlinker --export-dynamic' which adds all
symbols to the dynamic symbol table. So we should reproduce the problem
by setting NO_LIBPYTHON=1.

Disabling libbabeltrace check by default and replacing the
NO_LIBBABELTRACE make variable with LIBBABELTRACE.
Users wanting the libbabeltrace feature need to build via:
$ make LIBBABELTRACE=1
The reason for this is that the libababeltrace interface we use (version
1.3) hasn't been packaged/released yet, thus the failing feature check
only slows down build and confuses other (non CTF) developers.
