And was already done:

http://git.openembedded.org/openembedded-core/commit/?id=bc4d051c2fa56acb0479330b4342a39396de30d4

and it's not so error-prone, just call "bitbake world" in DISTRO without
x11 in DISTRO_FEATURES and fix all the ERROR: messages at the beginning.

See discussion around this change on ML and please don't remove stuff
just because you don't know/remember why it was added without at least
using "git blame" to read commit which introduced it.

Thanks
