That's not a typo ccache[1] is a compiler cache tool that can be used to speed up rebuilding object files. I don't know anything about the profile enabled builds but I imagine it has something to do with needing the 2nd build to produce difference object files from the first (with ccache enabled I imagine the 2nd build would result in identical output since on source files are changed between builds).
