openrc-force is masked in /usr/portage/profiles/base/use.mask:

    # Pacho Ramos <pacho@gentoo.org> (28 Sep 2013)
    # This USE flag is available after long dicussion in
    # http://www.gossamer-threads.com/lists/gentoo/dev/276077
    # to let some prople not able to run systemd to skip the dep (#480336).
    # Enabling this you will get a fully unsupported Gnome setup that
    # could suffer unexpected problem, don't expect support for it then.
    openrc-force

If you are unfamiliar with gentoo's profiles, most (all the
handbook-documented) profiles inherit the "base" profile which
contains this file, which means this mask is in effect on most systems.
None of the other profiles currently disable this use-mask. emerge's
output indicates to you that this use flag is masked by enclosing it in
parenthesis, check the documentation for the --verbose switch in
emerge(1)[1].

Use-flag masks from the selected profile (and the opposite, force)
override the use-flag settings normally made by users in make.conf and
package.use. User modifications to the profile should be made
in /etc/portage/profile/, see portage(5)[2].

To un-mask the openrc use flag, you can create the
file /etc/portage/profile/use.mask with this line:

    -openrc-force
