The linux-perf-* packages are intended to be coinstallable (though in
practice libperl sometimes prevents that).
We have a build-time test that all installed file paths are versioned:
! find $(DESTDIR) -name '*perf*' \! -path '*[_-]$(VERSION)*' | grep .
but now I see that that doesn't work because -path matches against the
full path, which includes $(DESTDIR), which includes $(VERSION).
