Well, I did end up doing this:

% cat /etc/portage/profile/packages
-*sys-apps/openrc

and creating the symlink as suggested.

I also added java-config-wrapper to package.provided as I originally suggested,
following the declaration of obsolescence in bug #549508.

So far everything seems to be working fine (i.e., gcc-config and
java-config-2 both work).

Thanks
