Josh Poimboeuf 60cbdf5d05 tools build: Fix objtool build with ARCH=x86_64
The objtool build fails in a cross-compiled environment on a non-x86
host with "ARCH=x86_64":

  tools/objtool/objtool-in.o: In function `decode_instructions':
  tools/objtool/builtin-check.c:276: undefined reference to `arch_decode_instruction'

We could override the ARCH environment variable and change it back to
x86, similar to what the objtool Makefile was doing before; but it's
tricky to override environment variables consistently.

Instead, take a similar approach used by the Linux top-level Makefile
and introduce a SRCARCH Makefile variable which evaluates to "x86" when
ARCH is either "x86_64" or "x86".

Wang Nan 935e6bd310 tools: Move Makefile.arch from perf/config to tools/scripts
After this patch other directories can use this architecture detector
without directly including it from perf's directory. Libbpf would
utilize it to get proper $(ARCH) so it can receive correct uapi include
directory.

Ingo Molnar 65fb09922d tools: Harmonize the various build messages in perf, lib-traceevent, lib-lk
The various build lines from libtraceevent and perf mix up during a
parallel build and produce unaligned output like:

    CC builtin-buildid-list.o
    CC builtin-buildid-cache.o
    CC builtin-list.o
  CC FPIC            trace-seq.o
    CC builtin-record.o
  CC FPIC            parse-filter.o
    CC builtin-report.o
    CC builtin-stat.o
  CC FPIC            parse-utils.o
  CC FPIC            kbuffer-parse.o
    CC builtin-timechart.o
    CC builtin-top.o
    CC builtin-script.o
  BUILD STATIC LIB   libtraceevent.a
    CC builtin-probe.o
    CC builtin-kmem.o
    CC builtin-lock.o

To solve this, harmonize all the build message alignments to be similar
to the kernel's kbuild output: prefixed by two spaces and 11-char wide.

After the patch the output looks pretty tidy, even if output lines get
mixed up:

  CC      builtin-annotate.o
  FLAGS:  * new build flags or cross compiler
  CC      builtin-bench.o
  AR      liblk.a
  CC      bench/sched-messaging.o
  CC FPIC event-parse.o
  CC      bench/sched-pipe.o
  CC FPIC trace-seq.o
  CC      bench/mem-memcpy.o
  CC      bench/mem-memset.o
  CC FPIC parse-filter.o
  CC      builtin-diff.o
  CC      builtin-evlist.o
  CC      builtin-help.o

Ingo Molnar 8ec19c0eba perf tools: Implement summary output for 'make clean'
'make clean' used to show all the rm lines, which isn't really
informative in any way and spams the console.

  comet:~/tip/tools/perf> make clean
   CLEAN libtraceevent
   CLEAN liblk
   CLEAN config
   CLEAN core-objs
   CLEAN core-progs
   CLEAN core-gen
   CLEAN Documentation
   CLEAN python

'make clean V=1' will still show the old, detailed output.

It looks at O= and adjusts the $(OUTPUT) variable based on what the
output directory will be. However, when O is defined but empty, it
wrongly becomes the user's $HOME dir which is not what we want. So check
it is not empty before working with it further.

David Howells bf35182ffc tools: Honour the O= flag when tool build called from a higher Makefile
Honour the O= flag that was passed to a higher level Makefile and then passed
down as part of a tool build.

To make this work, the top-level Makefile passes the original O= flag and
subdir=tools to the tools/Makefile, and that in turn passes
subdir=$(O)/$(subdir)/foodir when building tool foo in directory
$(O)/$(subdir)/foodir (where the intervening slashes aren't added if an
element is missing).

For example, take perf.  This is found in tools/perf/.  Assume we're building
into directory ~/zebra/, so we pass O=~/zebra to make.  Dependening on where
we run the build from, we see:

	make run in dir		$(OUTPUT) dir
	=======================	==================
	linux			~/zebra/tools/perf/
	linux/tools		~/zebra/perf/
	linux/tools/perf	~/zebra/

and if O= is not set, we get:

	make run in dir		$(OUTPUT) dir
	=======================	==================
	linux			linux/tools/perf/
	linux/tools		linux/tools/perf/
	linux/tools/perf	linux/tools/perf/

The output directories are created by the descend function if they don't
already exist.

Steven Rostedt c883122acc perf tools: Let O= makes handle relative paths
When I did a compile of perf using a relative path for the output
directory, the build failed when it tried to compile libtraceevent. This
is because it continues to use the same relative path when the new
working directory is in a different path.

    SUBDIR ../lib/traceevent/
/bin/sh: line 0: cd: ../../../nobackup/perf/: No such file or directory
Makefile:74: *** output directory "../../../nobackup/perf/" does not exist.  Stop.
make: *** [../../../nobackup/perf///libtraceevent.a] Error 2

Make the path used an absolute path when building perf with O=.

Boris:

Teach Makefile to check whether the supplied O= directory exists and
bail out if not. Reportedly, kernel dudes are idiots and need to be
guarded so as not to shoot themselves in the foot when playing in the
sandbox.
