By the way the profiling data is plain text and can be stored inside the
debian/ folder when making an Ubuntu package.  I imagine something
similar can be done for other package systems as well.

An alternative approach is to generate the profiling data at package
build time using a sort of "make profiledbuild" and giving it a script
such as yagmark.  This is more or less what Mozilla does, except it was
broken on Linux until recently and still isn't included in the Ubuntu
