    CI: build: skip sdk adapt to external toolchain on cache hit
    
    On cache hit, skip sdk adapt to external toolchain. This is needed because we
    cache the already extracted sdk and that is already adapted to be used
    as external toolchain.
    
    Rerunning the adap step will result in the test to fail for missing file
    as the file are already got wrapped to the external toolchain format.
