Subject: [PATCH v2 04/14] perf tools: Add kbuild support into Makefile.kbuild

From: Jiri Olsa <jolsa@...hat.com>

Adding kbuild support into Makefile.kbuild. The 'legacy'
Makefile still stays untouched as it was.

It's possible to use kbuild by running 'make -f Makefile.kbuild'
with any option supported by 'legacy' Makefile.

We now have 2 config files:
  '.config' - user configured setup
  '.config-detected' - system detected setup

The '.config-detected' affects '.config' and if there's
configured feature in '.config' which was not detected
it is automatically disabled.

The '.config-detected' is re/created if:
  - there's no '.config-detected'
  - '.config' was changed

In a cleaned tree the perf is built with 'allyesconfig'
having disabled all non-detected features, just as it is
done now.

You can change '.config' via:
  make -f Makefile.kbuild menuconfig

There's difference for O=DIR build. The DIR is populated
based on kernel source tree, so the final binary is created
under DIR/tools/perf.

This commit was originally created by Jiri Olsa in February 2013; a
few changes were necessary to fit the perf version of June 2014:
* Add missing CFLAGS for specific .o targets
* Update Kbuild files (new source files, ...)
* Fix recursive invocation of config/features-checks
* Store .config-detected missing variables (libdir, ...)
* Fix missing dependencies between Kconfig options
* Fix installation of traceevent plugins
* Fix missing cleanings of feature-check binaries
* CROSS_COMPILE was not used to define AS, CC, ...
* CROSS_COMPILE was not stored in .config-detected
* Take into account DESTDIR and prefix set in the command line
* Add missing Kbuild files for non-x86 architectures
  (powerpc, arm, arm64, sh, s390, sparc)
* Move perf-time-to-tsc.c into x86-specific tests directory
