commit e572d0887137acfc53f18175522964ec19d88175 upstream.
When doing a kernel build with 'make -s', everything is silenced except
the objtool build. That's because the tools tree support for silent
builds is some combination of missing and broken.
Three changes are needed to fix it:
- Makefile: propagate '-s' to the sub-make's MAKEFLAGS variable so the
tools Makefiles can see it.
- tools/scripts/Makefile.include: fix the tools Makefiles' ability to
recognize '-s'. The MAKE_VERSION and MAKEFLAGS checks are copied from
the top-level Makefile. This silences the "DESCEND objtool" message.
- tools/build/Makefile.build: add support to the tools Build files for
recognizing '-s'. Again the MAKE_VERSION and MAKEFLAGS checks are
copied from the top-level Makefile. This silences all the object
compile/link messages.

Add new rule to compile .cpp file to .o use g++. C++ support is required
for built-in clang and LLVM support.

In some cases, like for fixdep and shortly for jevents, we need to build a tool
to run on the host that will be used in building a tool, such as perf, that is
being cross compiled, so do like the kernel and provide HOSTCC, HOSTLD and HOSTAR
to do that.

The "man gcc" says .i extension represents the file is C source code
that should not be preprocessed. Here, .s should be used.
For clarification,
.c ---(preprocess)---> .i
.S ---(preprocess)---> .s

Making the fixdep helper to be invoked within dep-cmd.
Each user of the build framework needs to make sure fixdep exists before
executing the build itself.
If the build doesn't find fixdep, it falls back to the old style
dependency tracking.

It's sometimes useful to specify the object affiliation to multiple
config options like:
libperf-$(CONFIG_X86) += tsc.o
libperf-$(CONFIG_AUXTRACE) += tsc.o
while the object itself is linked only once. Adding the support for this
and ignoring duplicate objects in the object list.

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.

Invoking Makefile.perf with prefix= breaks the build since Makefile.perf
hands that variable down to Makefile.build where it overrides
prefix := $(subst ./,,$(OUTPUT)$(dir)/)
leading to errors like this:
No rule to make target '/usrabspath.o', needed by '/usrlibperf-in.o'

Allow nesting into directories without Build file. Currently we force
include of the Build file, which fails the build when the Build file is
missing.
We already support empty *-in.o' objects if there's nothing in the
directory to be compiled, so we can just use it for missing Build file
cases.
Also adding this case under tests.

Adding support to include detected configuration makefile into the build
process. This will allow the Build objects to be configurable based on
the config data, like:
perf-$(CONFIG_KRAVA) += krava.o
The configuration is stored in '.config-detected' file, which is
generated for each compilation.

Adding new build framework into 'tools/build' to be used by tools.
There's no change for actual building at this point, it comes in the
next patches.
The idea and more details are explained in the
'tools/build/Documentation/Build.txt' file.
I adopted everything from the kernel build system, with some changes to
allow for multiple binaries build definitions.
While the kernel's build output is single image (forget modules) we need
to be able to build several binaries/libraries.
The basic idea is that sser provides 'Build' files with objects
definitions like:
perf-y += a.o
perf-y += b.o
libperf-y += c.o
libperf-y += d.o
and the build framework outputs files:
perf-in.o # a.o, b.o compiled in
libperf-in.o # c.o, d.o compiled in
