 By setup I meant increasing the ccache size, although I didn't realize that 
LO build might fit if one builds without any debug info.

 This is not true if the build uses any kind of debug info, and I would find 
it a really nasty surprise that one would need to explicitly adjust ccache 
when enabling debug build. I think this feature is trying to be way too 
clever.
