Digging more into the command lines of the various HS files, they
include many generated sources and, also this folder:
build/<CONF>/hotspot/variant-server/libjvm/objs/precompiled
Now, I don't know exactly how ccache deals with PCH but I notices that
every time that the files in this folder are regenerated by the build
