Sorry, but not yet, tried to build it (the version that Jiri said worked
for him), after fixing up minor issues with blank lines being added to
the end of two of the files and then:

It builds ok if you do a build when CWD is tools/perf/, but who does

I'll try to fix this up later today, if you haven't done it by then.

Thanks,
