In general, in OE we build a whole lot of packages that aren't required
by the target image. Here, we already build dbus, even though it might
be disabled by an overridden config. Since both gnutls and openssl are
likely to be used by other packages, this adds no cost at all for many
targets, especially because only the library that actually gets linked
to is going to end up in RDEPENDS_${PN}.
