I think it is fine.  Of course if you want to go through additional pain
of teaching tree-prof.exp, you are very welcome to do so ;))
But in general profiling is not too much about warnings.

I would still preffer if we was able to simply default to profile
guessing when profile is unavilable but I see this is not 100% easy
right now, since many places still test global profile_info rather than
cfun->profile_status.  I will fix that incrementally.

The patch is OK.
