From: Jiri Olsa <jolsa@redhat.com>

Adding CONFIG_BUILTIN_* defines to govern builtin commands.
This will be usefull for kbuild process switch.

Pet peeve: #defines with a CONFIG_ prefix. Is that prefix needed here or
would another prefix also do? Or can these macros perhaps be added
through a Kconfig file (eg, as "config BUILTIN_REPORT" etc.). Or will
that happen at the "kbuild process switch"?

This is a temporary stepping stone to having them generated by kbuild.

Since you are not adding builtin-cmds.h as an included file this change 
takes away functionality. Each patch should ensure that existing options 
continue to work after the change.

ditto for all of the other changes to other files.

And I guess that, because of the typo in CONFIG_BULTIN_SCRIPT, that
would also be true if builtin-cmds.h were actually included.

From: Jiri Olsa <jolsa@redhat.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.
