perf also fails to build with:

Error 1

It looks like we need to backport 7a490187f22b ("perf sample: Add 
file_offset field to struct perf_sample") and pay attention to struct 
perf_sample being defined in tools/perf/util/event.h in this older 
kernel version, whereas the upstream commit modifies 
tools/perf/util/sample.h (which was introduced later).
