I concur with Daniel, I don't see anyone suggesting to drop the build
path from the .buildinfo file just yet. But as long as that field does
not leak information I'm ok with having it there. I think eventually
it should be dropped because nothing should be recording the build
path in the build, and the build should really be independent of that.

For now probably yes.

That's why I mentioned that the other language flages be included so
that we get better coverage besides C/C++.
