Weird.  I just ran through this, first with the default value for DISTRO_FEATURES,
then with the same value but 'ipv4' placed at the front of that list.  If 'ipv4'
is somewhere in the middle, busybox is not configured correctly.  If it's at the
front, it works properly.

A full log of these steps is attached.

What could possibly cause this behaviour?

Note: I printed the value of DISTRO_FEATURES by modifying base.bbclass.  Is there
an easier way to see the value of such variables being used by the recipes?  I gave
the bitbake manual a look, but didn't find any hints...
