    devtool: deploy-target: Avoid unnecessary dependency on awk on the target
    
    Relying on that awk is installed on the target just to extract the
    fourth column (i.e., the free volume size) from `df -P` is an
    unnecessary dependency for devtool deploy-target. As it is already
    using sed to mangle the output from `df -P`, this can easily be
    modified to only extract the free volume size.
