 I disagree with this change, as it does not improve anything for anybody. 
Ccache needs an explicit setup for LO anyway, so people who have already done 
their setup will need to adjust for this. People who only have ccache 
installed but haven't done anything will get slower builds, as the default 
ccache cache size is vastly unsufficient for LO builds, so ccache will only 
create cache contents that will be eventually thrown away without any use.
