    Make sure MACHINE(_ARCH) are exported for depend-cleanup.sh
    
    We run depend-cleanup.sh twice during the build. The second time is the
    normal run, where we run it under WMAKEENV and thus have CROSSENV's
    MACHINE(_ARCH)=${TARGET(_ARCH)} in the environment. However, the first
    time is for bootstrap-tools, where it's run under BMAKEENV and we don't
    have any assignments to MACHINE(_ARCH) in the environment, meaning the
    script sees them as unset. In practice this doesn't matter since the
    only use doesn't apply to bootstrap-tools, but it could be a future
    issue. Thus, explicitly export them for depend-cleanup.sh and have the
    script verify they're set.
