RFR: 8014074: Building hotspot with ccache in new build is very slow with empty cache.

I have mixed feelings on this one. On the one hand I don't like the idea
that using/not-using an optimization like ccache, changes the way the
build of hotspot is carried out. On the other hand, if this means we
will do more builds without precompiled headers then it should help trap
errors when there are missing #includes.
Does this have any impact on our actual RE builds?
