One of my containers, ubuntu:14.04.4-x-linaro-arm64, that build perf in
a cross-build env, failed to build, please take a look if what is in the
output below is enough for you to find the problem, perhaps you forgot
to add the new files grabbed from the kernel sources to the
tools/perf/MANIFEST file that is used to create the tarball that is then
used to test build it? I'll check that later, in a hurry right now.

Thanks,

- Arnaldo
