These are all good.  We're interested in compile speed across all
supported languages, so it's fine to do stuff that isn't C++.

If you can use oprofile to produce summaries for entire package
builds, I'd be very interested to see the results.  In addition
to the obvious user-space CPU cycle counting, it would be good
to see if there's any part of the kernel that gets hammered,
and get cache and TLB miss statistics.
