    ramips: do not "local" variables outside of a function
    
    Older busybox versions allowed using the local keyword outside of
    functions, whereas 1.25.0 (which was introduced in 06fa1c46fc32) do not
    allow this anymore (leading to the following error when executing the
    script: "file: local: line nn: not in a function").
