I would prefer not to make a build-time option of this, because then the
documentation has say something in line with "whether files are compressed by
default depends on how ccache was built", which I think would be unfortunate. I
chose to not include the --{en,dis}able-zlib option from the original patch for
the same reason. I think it's better to strive for good defaults and few
build-time options.
