This is so cool! Thanks!

At some point we'll remove these #elif, have all of then linked, so that
we can do cross-platform interpreting of perf.data files generated with
'perf trace record', i.e. 'perf trace -i perf.data.recorded.on.s390' on
a powerpc64 or x86 machine.

We're paving the way to that with patches like yours and those for
s/390, thanks again!
