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
