In order to solve the problem that libreoffice-5.2.0.4 is not yet
ready for liborcus-0.12.0, yet libixion and liborcus were updated
to 0.12.0, keep the previous libraries as libixion11 and liborcus11.
I hope that replacing libixion<0.12.0 with libixion11 and
liborcus<0.12.0 with liborucs11 works as I expect it.
