You can try building a recent perf and then using it on that old kernel,
there is no need to tie perf/kernel versions, the tool notices if
features it tries to use are not present on the kernel it is being run
and acts accordingly, falling back to using the features present in
older kernels.

If it doesn't work like that, we'd like to know.

So please grab the latest kernel sources and build the tool, then
transfer the binary to your target machine and try it.

If it still doesn't build, please report here.
