    phase1: move ccache preparation after defconfig
    
    The ccache.sh helper script uses make targets to figure out staging_dir paths
    which might trigger interactive menuconfig in case there is no populated
    .config file yet, leading to command timeouts on fresh trees.
    
    Move the ccache preparation step after defconfig in order to avoid triggering
    menuconfig.
