If you are in agreement over this, then I am happy to implement the change.

Wouldn't that be:

    perlarch .= ':any' if ($deps & (~(PROGRAM|PM_MODULE))) == $deps \
        and not $dh{V_FLAG_SET};

If $deps contains any of XS_MODULE or ARCHDEP_MODULE, then I presume we
should use "perl" rather than "perl:any" - even if there is a perl
script/perl module.
