[CentOS] Mate-update breaks locale

Hello All, 

today's Mate-updates seem to have removed our nl_be locale. 
We run Mate desktop on some 15 Centos7 laptops. 

Not so big a deal, we can easily switch to nl_nl or people would still figure it out in English. 
But maybe for other, not so common locales, you might want to check before updating. 

Greetings, Johan
