    IMPALA-12071: Don't download the ccache archive
    
    The ccache archive hasn't been updated in a long time,
    so it is useless. In future, we can come up with logic
    to keep the ccache archive up to date, but downloading it
    is a useless delay that doesn't result in cache hits.
    Set DOWNLOAD_CCACHE=0 to disable it.

>          Components: Infrastructure
>    Affects Versions: Impala 4.3.0
>            Reporter: Joe McDonnell
>            Priority: Major
>
> The toolchain build downloads a ccache archive at the beginning of the build. 
> However, the ccache archive is extremely old and cannot provide cache hits. 
> We should either update the archive periodically or we should turn off 
> DOWNLOAD_CCACHE.
