Cleaning everything and rebuilding we still end up with:
⬢ [acme@toolbox perf-tools-next]$ cat /tmp/build/perf-tools-next/feature/test-all.make.output
⬢ [acme@toolbox perf-tools-next]$ grep unwind /tmp/build/perf-tools-next/FEATURE-DUMP
feature-libunwind=1
⬢ [acme@toolbox perf-tools-next]$
I found a couple of problems with the patches that made libunwind to be
opt-in, I'm sending a patch shortly.
