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

'make clean' used to show all the rm lines, which isn't really
informative in any way and spams the console.
Implement summary output:
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.

Currently external addr2line tool is used for srcline sort key and
annotate with srcline info. Separate the common code to prepare
upcoming enhancements.

Separate out GTK codes to a shared object called libperf-gtk.so. This
time only GTK codes are built with -fPIC and libperf remains as is. Now
run GTK hist and annotation browser using libdl.

[ Fix it up wrt Ingo's tools/perf build speedups ]

If someone specifies a single target, mixed with O=, the following way:
hubble:~/tip/tools/perf> make O=/tmp/perf util/stat.o
BUILD: Doing 'make -j8' parallel build
gcc -Wbad-function-cast -Wdeclaration-after-statement -Wformat-security -Wformat-y2k [...]
The build might even fail, if a target depends on other targets:
hubble:~/tip/tools/perf> make O=/tmp/perf perf.o
...
perf.c: In function ‘handle_options’:
perf.c:155:21: error: ‘PERF_HTML_PATH’ undeclared (first use in this function)
The correct way to invoke such targets is:
hubble:~/tip/tools/perf> make O=/tmp/perf /tmp/perf/perf.o
BUILD: Doing 'make -j8' parallel build
GEN /tmp/perf/common-cmds.h
CC /tmp/perf/perf.o
But that's unnecessary typing and it's also easy to mistakenly build into the
source directory.
To fix this remove the generic suffix rules and add redirection to $(OUTPUT)
for the most popular .o targets.

To make it more apparent that there is not change in functionality we introduced
Makefile.parallel separately and now flip it with the main Makefile, which
moves into Makefile.perf.
The renames are:
Makefile.parallel => Makefile
Makefile => Makefile.perf
