Have you tried making the change?
spent an hour so a few weeks back. It is not trivial, but someone needs to find to fix it now. perf is the example to use: you can build it from both top level kernel directory (e.g, make -C tools/perf O=/tmp/perf) and the perf directory (cd tools/perf; make O=/tmp/perf). Both are wanted for samples/bpf and it would be nice to keep the O= option as well. I don't have the time for the next few weeks. Perhaps mid-June I can take a look.
