How is this built? Using O=/home/sfr/next/perf?

So I'm trying to revisit this, I did:
⬢[acme@...lbox perf-tools-next]$ rm -rf /tmp/build/$(basename $PWD)/ ; mkdir -p /tmp/build/$(basename $PWD)/
⬢[acme@...lbox perf-tools-next]$ alias m='rm -rf ~/libexec/perf-core/ ; make -k CORESIGHT=1 O=/tmp/build/$(basename $PWD)/ -C tools/perf install-bin && perf test python'
⬢[acme@...lbox perf-tools-next]$ git remote update torvalds

Then left this there and merged perf-tools-next:
⬢[acme@...lbox perf-tools-next]$ git merge perf-tools-next

I'm not being able to reproduce that problem, can you see where am I
doing some mistake in the above steps?
