Arnaldo,

I noticed you applied the patch to acme/perf/core, but it should be
instead in urgent since mainline is broken.

Now tested with:

 make O=... DESTDIR=... tools/perf
 make O=... DESTDIR=... tools/perf_install
 make O=... DESTDIR=... -C tools/ perf
 make O=... DESTDIR=... -C tools/ perf_install
 make O=... DESTDIR=... -C tools/perf
 make O=... DESTDIR=... -C tools/perf install
 make tools/perf
 make DESTDIR=... tools/perf_install
 make -C tools/ perf
 make -C tools/ DESTDIR=... perf_install
 make -C tools/perf
 make -C tools/perf DESTDIR=... install

No issues noticed, accept that doc is built when running the 'install'
target, not 'all'.

Will look at this.

We also should remove dependencies from install targets that trigger a
rebuild since 'make install' is run as root. I had a conversation with
Linus about this for building the arm kernel, but the same applies
also for perf tools. I don't have the time for changing this now, but
maybe in some weeks or so.

Thanks,

-Robert
