That still works:

$ cd tools/perf/
$ mkdir /tmp/pbuild
$ make O=/tmp/pbuild
    MKDIR /tmp/pbuild/arch/x86/util
    MKDIR /tmp/pbuild/bench
    MKDIR /tmp/pbuild/util
    MKDIR /tmp/pbuild/util/ui
    MKDIR /tmp/pbuild/util/ui/browsers
PERF_VERSION = 3.4.rc2.28.g7f953

...

    CC /tmp/pbuild/util/ui/helpline.o
    CC /tmp/pbuild/util/ui/progress.o
    CC /tmp/pbuild/util/ui/util.o
    AR /tmp/pbuild/libperf.a
    LINK /tmp/pbuild/perf
    GEN perf-archive

$ ls -al /tmp/pbuild/*.o | wc -l
