Probably yes, but coreutils is actually using $(copy_LDADD) today, and
I'd like to avoid forcing too much code churn on our client packages
whenever possible, at least when it is (like in this case) easy and
natural to do so.  Moreover, as I wrote in the commit message of the
first patch:

    Such a whitelisting capability is a good idea even regardless this
    motivation, since it helps enforcing the Autotools- philosophy
    "the user is always right" (as long as he is explicit enough).

Don't you agree with my rationales?
