On my preferred distros (ie Red Hat), ccache is used automatically;
there is nothing that needs to be done in configure AFAIK. (It looks
like this happens by dint of the same thing Alvaro mentions, ie the
standard PATH has /usr/lib(64)?/ccache in front of the actual compilers.)
It'd be important not to break such setups in trying to make it happen
elsewhere.
