[PATCH v3 0/9] perf build: Make build-test faster

[Wang Nan]

Utilise Jiri's feature-dump make target to avoid make build-test check
features too many times.

v2 -> v3: add $(O_OPT) to 'make clean' to ensure the correctness of
          config-clean.

Jiri Olsa (2):
  perf build: Add feature-dump target
  perf build: Introduce FEATURES_DUMP make variable

Wang Nan (7):
  perf build: Set parallel making options build-test
  perf build: Pass O option to Makefile.perf in build-test
  perf build: Test correct path of perf in build-test
  perf build: Pass O option to kernel makefile in build-test
  tools build: Allow subprojects select all feature checkers
  perf build: Select all feature checkers for feature-dump
  perf build: Use feature dump file for build-test
