This broke graphics/sane-frontends, and gscan2pdf by extension.

And this is why (beyond that, sane-frontends now throws quite a racket
during build because it relied on #include's in sane-backend's header
files which were "cleaned up" here as well).

On the other hand, there's only one port depending on sane-frontends
right now (gscan2pdf) and sane-frontends hasn't had an upstream release
in ages: if we can remove gscan2pdf's dependency on sane-frontends,
wen can (and should, really) retire sane-frontends. I'll check what we
can do here.

Regards,
Christoph
