Bug 269963: x11-toolkits/gtk30: Depends on accessibility/at-spi2-core despite
unsetting ATK_BRIDGE
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=269963



--- Description ---
/usr/local/etc/poudriere.d/hobbes-make.conf contains:

```
OPTIONS_UNSET+= AVAHI COLORD CUPS DBUS GCONF GSETTINGS JACK LINUX
OPTIONS_UNSET+= MDNSRESPONDER PLATFORM_WAYLAND PULSEAUDIO SNDIO
OPTIONS_UNSET+= WAYLAND
x11-toolkits_gtk30_UNSET+= ATK_BRIDGE
```

As I understand it, the above set of options *should* mean that gtk3 will be
built without depending on any ATK components. It did previously work this way.


And yet, `poudriere bulk -j 131_amd64 -z hobbes -c -vvv x11-toolkits/gtk30`
produces:

```

From looking at the gtk30 Makefile, it is not at all obvious to me where the
dependency that poudriere is reporting actually comes from. Details on how to
restore the previous behavior would be appreciated.
