Ok, but I think the spirit should be of being overly cautious with this
and check all the time if we are breaking it.

We need some tests for that, BTW, i.e. if something changes the function
signature, then the version should be bumped, etc.

Perhaps we build a binary that links to libperf and leave it there in
the sources, so that a 'perf test' shell can try to run it to get some
expected result only to catch that the ABI broke?
