Subject: [PATCH v4 13/14] perf kbuild: final cosmetic changes
* Correctly rename internal makefile variables
* Remove makefiles in tools/perf/config which became empty and useless
* Remove builtin-cmds.h
* Remove arch/x86/Makefile
* Improve outputs of clean and install targets
* Remove creation of PERF-FEATURES file which is redundant with the
.config file generated by Kconfig.
* replace HAVE_KVM_STAT_SUPPORT by a Kconfig option
* replace HAVE_SKIP_CALLCHAIN_IDX by a Kconfig option
* add Kconfig options for 32-bit compatibility VDSOs
Signed-off-by: Alexis Berlemont <alexis.berlemont@...il.com>

Changes since v3:
* Add Kconfig options for 32-bit compatibility VDSOs
