Comment (by pmetzger):

 I suspect it's doing that in order to have any knowledge of where the C
 compiler is located; it needs the C compiler sometimes. Do you have
 suggestions on what a clean way to deal with this would be? It still needs
 to know what the preferred C compiler is (and probably can't adjust that
 easily on the fly) but it obviously should not be using ccache. What's the
 right way to get that information?
