obvious question... are you sure DISTRO_FEATURES does not contain x11? did
you define you own distro config? it is there by default, so unless you did
something to remove it, it will be there.

you can display the value of the variable with

bitbake -e gst-plugins-base | grep ^DISTRO_FEATURES

you can check the value of PACKAGECONFIG as well to get more information.
