    gnu: ungoogled-chromium: Convert arguments to G-expression.
    
    * gnu/packages/chromium.scm (ungoogled-chromium)[native-inputs]: Remove
    the "master-preferences" gexp input.  Remove all labels.
    [arguments]: Convert to gexp.  Inline the above-mentioned gexp.  Remove one
    usage of "gcc" label while at it.
