Well, that sort of a amounts to the same thing, with a bit of work.

I am entirely ok with people who care about each platform looking at
what tar can be relied on, setting EXTRACT_USING to that if it is ok,
and if not setting it to bsdtar.

I think the difference beween Joerg's approach and mine is simply a
cleanup pass to say "If nobody said they are paying attention, force it
to bsdtar", and I'm ok with either approach.

So non-NetBSD pkgsrc users, please figure out your platforms!
