From: Arnaldo Carvalho de Melo <[email protected]> The 'tools/perf/test/make' makefile has in its default, 'all' target builds that will pollute the source code directory, i.e. that will not use O= variable.
The 'build-test' should be run as often as possible, preferrably after each non strictly non-code commit, so speed it up by selecting just the O= targets. Furthermore it tests both the Makefile.perf file, that is normally driven by the main Makefile, and the Makefile, reduce the time in half by having just MK=Makefile, the most usual, tested by 'build-test'. Please run: make -C tools/perf -f tests/make from time to time for testing also the in-place build tests.
