Well, ccache currently notes in the log file (if enabled) that it is has
been disabled before handing over to the compiler. And how to enable
logging? You can either set the CCACHE_LOGFILE variable or you can set
log_file in the configuration file... Another dependency on the
configuration is that CCACHE_PREFIX (prefix_command in the configuration
file) is applied even when ccache is disabled. So yes, I think it needs to
stay this way.

Sounds reasonable, I'll look into it.
