pkgtools.  Its main purpose is the support of pkgsrc, as it's unlikely
that users will also create alternative wrappers by hand.

Probably belongs in mk/ given that this will become a decently widespread

Bulk builds remove non-dependency packages with pkg_delete before building
each package.  So, as long as pkg_delete can do something useful, or the
fallback logic works correctly, all should be fine.

And we certainly want binpkgs generated by bulk builds to generate
alternatives on pkg_add.  8-)
