After I applied this I started getting this:
CC /tmp/build/perf/tests/sw-clock.o /tmp/build/perf/.plugin_jbd2.o.cmd:3: *** empty variable name. Stop. Makefile:192: recipe for target '/tmp/build/perf/plugin_jbd2-in.o' failed make[2]: *** [/tmp/build/perf/plugin_jbd2-in.o] Error 2 Makefile.perf:591: recipe for target '/tmp/build/perf/libtraceevent-dynamic-list' failed make[1]: *** [/tmp/build/perf/libtraceevent-dynamic-list] Error 2 make[1]: *** Waiting for unfinished jobs.... CC /tmp/build/perf/tests/mmap-thread-lookup.o
If I remove the O= build dir and restart, I get it again:
[acme@jouet linux]$ rm -rf /tmp/build/perf/ ; mkdir -p /tmp/build/perf ; make -k O=/tmp/build/perf -C tools/perf install-bin make: Entering directory '/home/acme/git/linux/tools/perf' BUILD: Doing 'make -j4' parallel build

Trying to nuke my ccache dir:
