No, error message says you should not supply a ccache wrapper as
compiler. Since the typical reason for supplying a ccache wrapper is to
get a ccache enhanced build, the message says that the proper way to
achieve this is to use --enable-ccache.

If you just add --enable-ccache, you're not doing this "instead of".
